My largely lore-free collection of thoughts on season 2. I'll post a more lore-centric review later on. In this post I'll only mention lore gripes where they create immediate confusion within the scope of this show's plot and established timeline.
Time & Pacing:
Pacing was a major struggle of season 1. Season 2 managed to up the pace of event significantly, sometimes too fast. As they upped the pace, they sacrificied any clarity of timing and timeline instead. I'm not one to bitch about "fast travel" (and this show definitely uses that), but it goes well beyond not showing characters travelling along established routes between events. The show is really unclear about how long passes between events, what things take time, and what is happening concurrently with one another. Characters just appear in different locations as needed by the plot, with no sense of the passage of time or how their movements impact the world around them. The other two areas that seem to have any latency of movment or communication seem to be Lindon and Eregion, and that was largely a plot contrivance to explain how Celebrimbor could be fooled by Halbrand before he took the form of Annatar.
To carry this to the extreme, the opening scenes of season 2 episode 1 largely imply that the entirety of the Second Age of Middle Earth took place in the lifespan of black goo Sauron and Halbrand. Obviously the 2nd age lasted longer than the disguised life of a mortal man, but the show does a really poor job of depitcting that (and those scenes break its own internal canon in other ways I'll get to later).
Dumb and Cartoonish Characters:
The characters just did whatever the plot needed them to do, without very little internal logic, consistency, or character development. This applies to both individual characters, and larger groups. Elrond pretty much spelled out exactly the Sauron's plot with the rings, yet Galadriel and Gil-Galad still decided to use them anyone despite knowing they were made by Sauron. Adar learned that Halbrand was indeed Sauron, yet continued to do exactly what Halbrand had told him to do. The very elf that sees Sauron's form in the unseen realm is the one that he manages to persuade to his side most eagerly? Galadriel's plan to escape with the nine rings safely from Eriador was... to bring them to the Orcs herself? Durin III refused to send out his army to defend Eregion because of the threat of Durin II's mining, but then confronted Durin II alone (without that army he held back), before eventually sending out the army with Narvi at the helm while he stayed in Khazad-Dum. Why not just send the army out under the command of Narvi in the first place? And, perhaps worst of all, the Numeneoreans basically switched allegiances and belief structures basically every episode. I know canonically that the Numenoreans end up being kinda dumb by the end of the second age, when they literally end up building a Temple of Melkor, but this isn't so far as that event yet and the rapid back-and-forth switching of power and allegiances between Pharazon and Miriel felt so forced and ridiculous. Pharazon's scheming would have played so much better as a slow burn with more consistent scheming and ground shifts than what was essentially a continuation of the "elves took ur jerbs!" scene from season 1. It becomes exceedingly hard to care about characters when they repeatedly engage in unbelievable and cartoonish behavior.
Too Many Meaningless Sideplots:
Did you miss Theo or Isildur or the Harfoots when they would go missing for episodes at a time? Nope, neither did I. Hell, they killed off of the larger side characters from season 1 off-screen between seasons, as a further example of the bloat. Even Galadriel and Elrond ended up getting sidelined for entire episodes because there were too many plotlines to be serviced. The Numenor plotline largely fell flat, but it's essential to the tale of the second age. Jamming in Gandalf, having an Isildur death fake-out with random romance side quest, a random Shire origin story nobody asked for, and continuing with the adventures of the random invented characters from season 1 as they escaped from Mordor all are not essential - and have largely come at the detriment of the rest of the show.
The Sins of Season 1:
Much of this season suffered from the decisions made in the previous season. Sometimes it strove to correct those mistakes, occasionally veering into overcorrection territory (Galadriel literally becoming a damsel in distress as a glaring example). But having to try and salvage the inconsistent plot points and logic of the previous season often painted them into corners that resulted in dumb characters and absurd plot contrivances. The relationship between Celebrimbor and Sauron/Annatar was unquestionably the highlight of this season, but in the process it just highlighted how terrible the decision in season 1 to omit Annatar in favor of "Halbrand" was (and the showrunner's terrible explanations for it), and season 2 had to arrange a host of ridiculous plot contrivances to explain how Celebrimbor would be fooled again by Halbrand/Annatar and the Elves would use the rings (despite them being forged out of order and with Galadriel's knowledge of Sauron's involvement). There are countless other examples all around of the show trying to dig itself out of the hole season 1 created. The Numenoreans colonies are suddenly a thing again, despite season 1 making a huge deal of them sailing to Middle Earth. Entire character plotlines were jammed in because they didn't know what to do with Adar, Theo, Isildur, or Arondir after season 1. Honestly, they probably should have just Bronwyn'd a few more of them off screen.
The Absurdities of this Timeline:
So many things just don't make sense in the greater scheme of things.
Both the Dwarves and Elves have seen the power and effect of the rings, why are they going to keep using them? In particular the Dwarves.
Are the Dwarves just going to ignore the Balrog in their basement? How is it going to be a surprise that it has led to the destruction of Khazad-Dum thousands of years in the future in the Third Age? The Khazad-Dum timeline changes are just a mess.
Gandalf being around in the Second Age still doesn't make sense, particularly considering how many times he's near the One Ring during the Third Age before he realized it.
If the Dark Wizard is Saruman (and given what they did with Gandalf, it's probably Saruman), how are they going to explain Gandalf following him for essentially the entire third age?
Even within the show's own itnernal timeline - season 1's intro established that Sauron "spread Orcs to every corner of Middle Earth" after the fall of Morgoth, and used Sauron's reign over the Orcs as the establishing rationale for Galadriel's hatred of Sauron as she wanted vengeance for Finrod. Yet in season 2, we see the Orcs immediately kill Sauron as he tries to claim power over them after Morgoth's defeat. The show is already retconning itself, and in ways that make little sense.
Other Random Thoughts:
So many shitty one liners that just don't connect. S1 had the "I'm good!" and now we get "Heal Yourself"
So many deliberate references to the Jackson trilogy, and each time they feel so jarring and out of place. Either live on your own merits or live on the merits of Tolkein's original craft - don't try and live on the merits of a better adaptation.
In something that highlights both of the previous points together - I was really enjoying Celebrimbor's final moments.... until he literally said "you are the Lord... of the Rings." What a way to shit all over what should have been a highlight. A scene that went from being terrific to utterly horrid in an instant.
Why is Sauron so horny? His affections for Galadriel in both S1 and S2 were already non-sense, but then we got him lusting after some random other elf just because she looked like her.
The random romances in this show pretty much all fall flat. Durin and Disa is the only one that works. They really are the beating heart of the show.
We had that big troll show up and get an intro scene, and then he only showed up again for one brief moment to do nothing of actual consequence.
At least it was usually pretty to look at.
The first instance of Tom Bombadil was pretty great, but it's largely because they were cribbing his dialogue straight from Fellowship of the Ring. Then they turned him into Yoda from Empire Strikes Back, and it was beyond cringe.
How convenient that the Orcs strapped something flammable to their one and only siege weapon capable of taking down the walls so the Elves could shoot fire arrows at it.
Cirdan really captured the spirit of Tolkein's Elvish dialogue so well. I wish we had seen more of him.
How did Arondir survive being stabbed at the siege of Eregion?
Most of the combat was fairly entertaining to watch. But the repeated dudes getting kicked into trees/rocks/etc. always looked cheesy. It kinda worked when Berek the horse did it, because it's supposed to be a bit goofy. But Galadriel and others doing it was really painful to watch.
Aside of a select few moments, the show felt "small." The gatherings in Numenor, Eregion, etc. always felt like it was a couple dozen random extras. You can count the crowds gathered by hand.
The moments that did feel grand stood out and felt meaningful. Durin's speech in Khazad Dum is the highlight of these.
Why did they use CGI shots of Adar's face for his biggest dialogue moments in episode 7? Felt out of place in a show that has largely used prosthetics and costumes.
I'm going to miss Charles Edwards as Celebrimbor. He really made the role his own and played it well.
The Rhun mercenary dudes were mostly wasted, but the wardrobe department really nailed their costume design.
They also brought back the random Sauron-worshipping "Nazgals" were brought back as servants of the Dark Wizard... and did a whole lot of nothing.
Gil-Galad might finally do something in season 3? Hopefully?
