I did a full re-watch through the films recently (sort of middle of the night baby stuff) and I had a few changes of heart on a number of things. I think two movies in particular were better than I remembered them, and one was worse.
1. Captain America: Civil War
-Originally I thought it was just a few loosely connected set piece battles, but similarly to how some people approached Infinity War, it's more interesting to watch it with Daniel Bruhl's Zemo as the focal point.
-As he says, he knew he couldn't defeat the Avengers himself, but could he get them to defeat themselves? That final line where he's mocked by Agent Ross about failing so spectacularly - "Did I?"
-Ultimately, he came as close to defeating the Avengers as anyone, as just an ordinary man. It took Banner to actually contact Steve Rogers in the Infinity War Saga - Stark couldn't even do it himself.
-A good superhero movie needs a good villain and I think he did a fine job. I think the MCU has a tendency towards BIGGER = BETTER so it's creative to have a regular person step up and rip them apart.
2. Avengers: Age of Ultron
-I disliked this movie originally, and it certainly still has its awkward moments. I still don't like how the twins were used in the film.
-I've come around to appreciate James Spader's Ultron, but I think it's mainly because I like James Spader. It's basically just him in a metal suit (pretty much exactly as he's been in the Blacklist or Boston Legal), so if you don't like James Spader, you aren't going to like Ultron.
-I find his peculiar mannerisms unique, differentiating him a bit from a more conventional BBEG like Thanos who is generally stark and gloomy and dire for the most part.
-The film's opening sequence followed by the party does a good job of showing the progression of their interactions with each other, becoming more familiar and cozy. The original Avengers was obviously their formation movie, but a lot of the dialogue and interactions are pretty wooden in that flim as a result.
-On another note, does Andy Serkis just knock any role he plays out of the park? The guy is a total chameleon. I'm glad he got another go in Black Panther.
-The flying city is actually quite impressive visually, but the endless robot fight is just a rehashing of the endless Chitauri fight from the first movie.
3. Avengers - Infinity War
-I already knew the Infinity Gauntlet storyline before watching this, so it's wasn't much of a surprise or shock when it came to the ending.
-Thanos himself might be the only really interesting part of the film, and I know people have said that you should approach it as his movie (kind of how I advised approaching Civil War).
-Re-watching this, I found it fairly boring. It reminded me of the first Avengers movie. I didn't really care for the Children of Thanos as villains, and it just sort of jumps around from CGI overload battle to CGI overload battle.
-Endgame does such a better job of delving into the emotions of the characters from beginning to end.
