Part 1 was largely whack af. Only real highlight was the Erza cameo (which got completely spoiled for me cuz my jackass friend that doesn't even watch the damn crossover), and seeing Lex continue to ham it up. Pretty much nothing happens until the final 10 minutes, and (unsurprisingly at this point) the final fight against the Anti-Monitor was very underwhelming. Especially compared to Earth X, that boasted a much bigger cast for the big battle.
Ryan Choi being one of the paragons still felt random due to him being a newly introduced character, they should've introduced before this crossover. And I just straight up didn't like Arrow becoming the Spectre. Everything about that was handled poorly and it felt very boring. All I can really say is I guess his 2nd death was a little better than the first?
Part 2 starts off on a better note, in that it at least finally achieves at least the goal of bringing Supergirl and her cast on over. That that also included the detail of Lex being in control of the DEO, as well as a respected figure, was very interesting. It started to get kind of annoying though having to go through the process of J'onn restore the memories of several characters though. Was seeing some good ol' Legends banter (and some actually enjoyable crossover dialogue) tho, same for the giant Beebo callback. Main issue with this episode though is that it feels more like an epilogue. Which maybe could've worked... if Part 4 actually felt appropriately climatic. I mean yea they fight Anti-Monitor again, and it was slightly better than Part 4... I guess, but at that point I'm just more interested in seeing everyone adjust to Earth Prime. Fuck the Anti-Monitor, Lex was a better antagonistic force.
Though Oliver's 2nd death still felt somewhat lacking, seeing the president, cast, and effectively the whole world honor Oliver's sacrifice actually got to me. That was genuinely emotional.
Was annoyed that Black Lightning got the short end of the stick in terms of screentime, but they made up for it by confirming he's also a part of Earth Prime, as well as a founding member of the Justice League (!!!) Also the "Oh it's like that?" line had me dying 😂
Overall, I consider this crossover to be a huge disappointment for the most part. Also didn't help that the break just killed any hype, not that the final two episodes really deserved it. The Anti-Monitor just didn't feel very threatening, there was arguably too many damn cameos (As in, the ones that took up ample screentime) as well. But at least I can take solace in it not copping out or half-assing actually combining the worlds like we all wanted.
