Oh GOD, was there way too much crammed into BvS. Though I think it is past the statute of limitations on movie spoilers, here is a warning anyway.
First of all, they should be trying to salvage Superman's image a bit after some people had issue with his killing of Zod and not trying to take the fight outside the city, which they failed with right off the bat when he superspeed crashes into that African warlord and drives him through a concrete wall and everything behind it. It's also so convenient how he can instantly reach Lois anywhere on Earth if she's in danger, but fuck Jimmy Olsen, right? And fuck his mom, too, since apparently his super hearing doesn't work through warehouse windows.
Second, introduce the new Batman. Third, introduce Wonder Woman. Fourth, hint at the other JL members with the videos. Fifth, have the movie be the ending of The Dark Knight Returns comic. Sixth, actually, let's throw in The Death of Superman as well. Seventh, hint at what villains are in store in the future franchise movies by giving Batman prophetic dreams and possibly throwing in a Flash Point. We are setting up a franchise, you know, so it's important to do this stuff!
And then there's Luthor. There were moments of brilliance to Eisenberg's characterization of Luthor, but sadly they were overshadowed by the rest of the performance which lay between stupid and annoying. Plus, in no way was he what anyone expected when they think of the character of Lex Luthor. It appeared obvious that he was aware of the identities of Batman and Superman, but there's no indication of how he came by this information. Maybe he did the same legwork Lois did in Man of Steel to figure out Clark and Superman are one in the same, but no idea about Bruce/Batman. It also seemed apparent he set up the kryptonite to be stolen by Batman in order to give him the ability to defeat Superman. But then he also makes an uncontrollable killing machine and sets it loose for the hell of it? What!? That makes no sense!
Affleck as Batman was great. We got a hint of how he may have changed into a killer by the desecrated Robin outfit, that warehouse scene was probably the best action sequence of the entire film, and his training regimen made Bale's push-ups look laughable. Though it is also as laughable to think he was so inspired by Superman's (stupid and needless) sacrifice that he'll change his ways, which was the feeling I got at the end of the movie. Gadot was great as Wonder Woman, though relatively absent for most of the movie. I'm glad we got to see her really shine in her own film. Cavill remains rather boring and dull, though a large part of that I blame on the writing and direction. The best scene of him, and really the most human part of the entire movie, was him climbing into the bathtub with Lois. It felt real and showed a level of intimacy and comfort between the characters that did not exist anywhere else.
God, the movie was such a clusterfuck, and here I'm thinking I might see it for a second time since my brother-in-law has not seen it yet. I'm slightly curious about the director's cut, which supposedly clears up a number of issues, but I fail to see how making an already too long movie even longer is a good idea. Guess I'll find out one of these days.
