Saw it on Friday and give it a solid A-. There's some things - the pacing, the dourness of Superman, and Eisenberg's Luthor - that could've been better, but overall I really really enjoyed it. And with Luthor, I'm aware that he's the son of the "proper" Lex Luthor so that helps... somewhat. Another nit I'd pick is that I'm not entirely clear on Batman's state - specifically, his family life pre-Superman. He's meant to have been married and lost his wife in the Metropolis attack? Is that little girl meant to be his daughter?
But overall what an impressive take on Batman and Bruce Wayne as a cynical, worn-out, tired older crimefighter who's lost Robin and is being pushed to extremes out of despondency. Some great interplay between him and Alfred. I really liked how he started out in such a dark place but seems to be edging back towards the light by the end.
The highlight though was Gal Godot as Wonder Woman surprisingly. Even for as little screen time as she got, she glowed and when she enters the fray to save Batman and take on Doomsday, it was fantastic. I'm
so ready for her movie now.
Another thing that really really worked for me was using Martha's name to defuse the fight between Bats and Supes. I'd never picked up on the coincidence of Martha Wayne and Martha Kent both, so it took me by surprise. And what better way to shock Bats into backing off for a moment than by first throwing him back to his mother's death (who he couldn't save), then making a connection with this Alien. Probably my favorite moment of the movie, to be honest.
ETA: Despite not generally caring for this take on Lex though, I do have to admit I was blown away (ha...ha... ha...) by the audacity of his plan to get rid of the Senator. Although: does that mean no more Mercy Graves? Already?
