Doing movies separately because I haven't watched all the shows yet and I think it's weird to stack up long form stories against films to begin with. I'll try to mix it up with brief reviews for each)
Tier 1 (best of the best)
Guardians 1 (For me, the only flaw is I've rewatched the movie so many times that the jokes have no ability to make me laugh anymore. The same parent company tried and failed to deliver on the new Star Wars trilogy and somehow Guardians of the Galaxy delivered on a high concept sci-fi adventure that a lot of people were hoping for with new Star Wars. It's a tightly crafted adventure with strong humor, a killer soundtrack, charming characters, and fun iconic moments. Someone could watch this movie without having seen a single MCU film and have a great time. You can't say that about a lot of MCU titles, including other movies in this tier)
Avengers Infinity War (it's not a perfect movie but the Russo brothers should be and are rightfully commended for so deftly weaving so many storylines, with so many characters, through so many huge and bombastic moments. This movie, more than any other, is worthy of the namesake. It's a marvel that this movie works as well as it does. Thanos in this movie is an all timer of a comic book movie villain and Brolin was incredible)
Captain America 2 (the helicarrier stuff at the end is a bit over the top but otherwise it's an extremely well crafted example of a grounded and (relatively) realistic superhero adventure. I don't agree with the common classification that this is a "spy movie" though and I really don't understand why people think it is. There's quite literally zero espionage/spy intrigue of any kind here. Historical/pseudo political intrigue is not the same as spy intrigue)
Iron Man (for my money, this is the crown jewel of superhero origin stories. The final conflict is a bit dumb if you think about it hard enough, but RDJ's introduction and journey to become Iron Man is just such a treat to watch. It didn't write the formula for a superhero origin movie but it set the bar on the quality and I don't believe that bar has been met since)
Guardians of the Galaxy 3 (I don't really have a lot of complaints. A few jokes here and there weren't bangers. Some of the scenes with the talking animals felt like direct emotional manipulation. But past that, it's a stellar ride of a sci fi adventure and a properly executed emotional send off for (most of) these characters)
Thor Ragnarok (Love and Thunder makes me wonder in awe how Waititi executed such a tight, fun, funny, and visually pleasing superhero movie. I don't really have complaints. I just enjoy the other ones above it a bit more)
Tier 2 (really good but flawed)
Avengers Endgame (Certain elements of the time travel act are a bit too wonky, the girl power team up scene where all the female heroes magically happened to find each other on the same spot on a massive battlefield was eyeroll inducing (I'm not against having a scene like that but they did it in Infinity War in a much more realistic and believable way), fat Thor was a cheap vehicle for lazy fat jokes. These things drop it to tier 2. But the movie still hits hard on so many emotionally raw moments very effectively and the big battle at the end is still a fun ride)
Captain America Civil War (I think the quality of the story has dips here and there but having it over the Avengers is the product of my appreciation that the Russo Brothers at least made a half decent attempt to infuse real dramatic stakes into an ensemble superhero clash flick. It doesn't hit the mark everywhere it could have but I'd rather rewatch this one than the OG Avengers movie. Substance wins out for me. Sorry not sorry)
Avengers (I think nostalgia goggles give this movie more favor than it deserves. No question it's a fun ride, but if there's any movie in the MCU that I'd concur with the idea that superhero movies are the movie equivalent of amusement park rides, it's this one. On multiple rewatches you can start to see the formulas and calculations to maximize audience thrills and it cheapens the quality overall)
Deadpool and Wolverine (the conflict with Cassandra Nova is a bit disappointing but I think it's a fun time. It's lacking a bit of the cynicism and edge of the first 2 Deadpool movies but I don't think that's necessarily a bad thing)
Thunderbolts*/The New Avengers (I'll stand by it that this movie works well. The last act is a bit cheesy but having struggled with depression I actually think the high concept inner Void stuff served as a vehicle to depict mental health struggle in a raw and visceral way. Yelena Belova earns her right to be a marquee MCU character with this one at a time where the MCU has struggled to sell me on who the core Avengers will be replaced with imo. If Yelena is the next coming of Black Widow and a de facto leader of the next group, I am okay with that)
Spiderman Homecoming (I just think it's a solid and fun (proper) intro to Spiderman in the MCU. The stakes aren't that high, the big battle isn't too over the top but I think that actually serves the movie well. This isn't a fully fledged spiderman yet so it's not a fully fledged conflict. But that does also limit is place on my rankings a bit)
Black Panther 1 (another last act curse. Strong movie for the most part until an underwhelming-to the point of deflating-last act)
Spiderman No Way Home (putting aside that the movie doesn't hold up as well for home watching given how some scenes were cut to allow the audience to cheer, I think the multiverse stuff set a strong backdrop to give Holland real dramatic meat to chew on with the role of Peter Parker and I honestly believe he did a great job. It's fun. It's a good ride. It's not the highest quality product or best Spiderman story though)
Guardians of the Galaxy 2 (I don't really have a lot to complain about. Imo Guardians is the strongest trilogy in the MCU but this is just the one I'd want to revisit the least. It's a good adventure, it's entertaining, it's humorous, it has heartfelt moments, but there's just something about it that's left wanting)
Tier 3 (pretty good to decent)
Captain America 1 (the first act is terrific. Middle act is a bit meandering. Third act is unremarkable and unsatisfying until the moment Rodgers has to put the plane in the ice. The final scene is the best final scene in the MCU including the end of Endgame which is a direct resolution of this movie's ending. High marks for the characterization work for Steve Rodgers that carries through for the entirety of his MCU run)
Dr. Strange (has the stink of an extremely generic origin story structure but I can't deny that it also included some of the coolest and most imaginative CG work not just in the MCU but in the landscape of blockbuster movies in general. Cumberbatch was solid as the protagonist)
Iron Man 3 (the fake out villain and real antagonists did nothing for me. The extremis concept was also dumb to me. But I give credit to them writing a strong journey through trauma and anxiety for Tony and RDJs performance was outstanding. Some of the action sequences were really cool)
Shang Chi (kind of by the numbers. Some stupid story beats. The martial arts in the first half were fun for me and I had fun with the last act even if it was a pretty generic big CG battle)
Black Panther 2 (higher marks for tonally acknowledging the death of Chadwick/Tchalla but beyond that it's a fairly weak MCU story. Shuri doesn't earn the role of Black Panther, imo. I did not like Ironheart. Villain was okay)
Ant Man (it's just fine. MCU by the numbers. Rudd is fun in the role. The adventure is fine. Villain is unremarkable. Inoffensive and safe. Fine)
Spiderman Far From Home (I think it gets more flak than it deserves. Parker's struggles to have a normal teen life create some amusing moments and I actually enjoyed the conflict with Mysterio. That said, it feels like it could have told a more compelling, purposeful, and focused story).
Avengers Age of Ultron (on paper, the story is great, a lot of the moments are worthy of the Avengers billing, and there's some strong performances. But somehow, as a sum of its parts, it's just meh. I don't know why. I've tried rewatching and it never improves for me. The weakest Avengers movie to date)
Captain America 4 (it's just fine. I liked it more than Cap&Winter Soldier the show, but the last act is just whatever. I'd rewatch it someday but it felt like a movie they were obligated to make and only kind of delivered)
Eternals (some really cool moments and a solid story with an underappreciated score, but overall the movie failed to make me care about any of its characters. If I don't see one of them in the coming Avengers movies, I wouldn't be longing for anything)
Tier 4 (just okay to meh)
Thor: (it has a certain charm to it but it's just underwhelming compared to other Marvel movies above it)
Captain Marvel (run of the mill origin story, completely unremarkable outside of the alien cat. Larson is almost entirely devoid of any charm and it's that much more apparent when you have an in universe character like Kampala Khan be so likeable and charming. And Danvers is supposed to be her idol?)
Ant Man and the Wasp (competently made. Some solid jokes. Almost entirely forgettable without looking things up. I know I watched it. But if I passively try to remember anything, it's like the movie didn't happen.)
Black Widow (aimless and generic "normal human"/Bourne-esque first two acts. The movie stumbles from that mediocrity to get even worse when it's time to reveal Natasha's backstory with a meandering and unsatisfying third act. Yelena Belova is the only real reason to give it the time of day. Feels like a half baked attempt to give an undercooked character (who was initially brought in mostly as eye candy) more depth and backstory after her character is killed off)
Dr. Strange 2 (just misses the cut on bad. There's some stellar cg visuals and some fun action sequences but there's also some excruciatingly bad writing in there)
Tier 5 (bad)
Thor Dark World (just shy of meh. Truly forgettable antagonist, tonal inconsistencies, and characterization inconsistencies with the supporting cast drags it down a lot. Felt aimless and made just for the sake of it)
Iron Man 2 (Rockwell is fun and RDJ is always a treat, but the movie is blisteringly stupid with an unremarkable final act)
Ant Man Quantumania (huge exercise in wasted potential. A movie with a bunch of set pieces they came up with before locking down the story resulting in top to bottom writing disasters. A few decent performances and action moments aren't enough to save it)
Thor Love and Thunder (arguably the most massive disappointment of the MCU given how terrific Ragnarok was. Wasted the potential of Gorr, the potential of the Guardians, Jane Foster as Thor, and riddled with aggressively unfunny jokes to the point where I honestly wonder if Waititi was intentionally mocking the audience and giving the finger to Marvel/Disney)
The Incredible Hulk (feels excessively out of place in the MCU and not just because of the Banner recast. Norton is a great actor but was an excruciatingly dull and lifeless Bruce Banner. The story as a whole is forgettable at best, awful at worst. It's closest thing in the MCU to the Sony disaster run of a Spiderman adjacent superhero universe though I'd put Venom 1 above it)
Have not watched yet: The Marvels. (I liked Kamala Khan in her show but I just do not give a flying f*** about the Captain Marvel branch of the MCU narrative beyond her. I'll watch it eventually)
Shows I have seen
Loki Season 1 (I think the TVA stuff is kinda dumb but it's strong nonetheless) 8/10
Wandavision (last episode is a brutal faceplant on an otherwise strong and unique concept. The manufactured trauma and tragedy of losing fake children she invented and lived in her head with (for just a few days without years of watching and helping them grow) being such a driving force for Wanda turning evil started here and I think it's one of the stupidest story beats the MCU has ever come up with. But the show was really strong up until it came up to its reveals) 7/10
Agatha All Along (Last episode was a drag. Solid stuff otherwise) 7/10
Hawkeye (I actually like it more than most seem to. Kate Bishop is charming. The story is fun. It just could've been better) 7/10
Ms. Marvel (first three or so episodes are solid. I like Kamala Khan more than Carol Danvers by many degrees. But the show stumbles hard when the real conflict starts developing) 6/10
She-Hulk (Jen is a fine and charming character but so many plot threads are dumb, dialogue is often dumb. Does not make me want to see more of She Hulk going forward. The only episode I really liked was the Daredevil episode) 5/10
Moon Knight: so underwhelming I forgot I watched it until I saw it on other lists. Cool concept. Love Oscar Issac. Forgettable as demonstrated. (5/10)
Cap and Winter Soldier (the dramatic conflict is uninteresting to me and that's the best thing I can say about it. The whole thing with trying to make the terrorist group sympathetic rubbed me the wrong way and having Sam's sympathies for them culminate with him delivering a poorly written lecture to a senator, it was just extremely disappointing. I'm rooting for Sam to succeed as Rodgers' successor but I felt this show did him a disservice and I'm not opposed to the MCU hitting on contemporary issues but it felt like there was more intent to do that than thoughtful execution) 4/10
Xmen 97 doesn't count does it? If it does that's number 1
Watched one episode of Loki Season 2 but wasn't ready to sit down with it. Watched one episode of Secret Invasion and it failed to rouse my interest to continue. Haven't watched Daredevil because I'm still behind on a lot of the Netflix stuff. Haven't watched Daredevil S3. Didn't finish Punisher Season 1. Haven't watched season 2 of Jessica Jones and didn't even know there was a season 3 until today. Didn't watch Luke Cage. Wish I hadn't watched Iron Fist and I think that show is the reason I haven't gone back through the "Netflixverse". Didn't watch the team up. Haven't watched Echo and forgot it was released.
