I liked a lot of things about BvS. The fight scenes and cinematography were amazing. I LOVED Wonder Woman’s introduction and music. I liked seeing Clark investigate he Batman as a journalist in the extended version. I liked that Bruce Wayne actually seemed to do stuff other than be a facade.
I thought the movie tried to do too many things. The clips of future Justice Leaguers could have been the post-credit scenes. A lot of the dream sequences annoyed me (Pa Kent gave a morose story and was a waste of time IMO, Bats shouldn’t need Flash to tell him that Lois is important in the future, and Knightmare… was an OK way to showcase Bruce’s fears about Superman, but he should know not to just act on ‘what if’ fears, and (in hindsight) there was no payoff in Justice League to make the time devoted to the Knightmare worth it). I thought Batman was manipulated too easily into fighting Superman. I didn’t like Batman using guns and branding people; this didn’t kill the whole movie for me, since I knew they were referencing the older, more jaded, more violent Batman from Miller’s stories, but I think they took the violence too far. As for the ‘realizing Superman’s humanity’ moment (aka Martha!), I saw what the film makers were trying to do, but I don’t think it was particularly well executed. For example, Superman’s power levels still gave him at least a 1% chance of becoming the Knightmare version, regardless of how much he loves mom - perhaps mom’s death is what drives Superman to Knightmare-Superman a la Injustice. For as far gone/against Superman as Batman was portrayed earlier in this film, he seemed to turn around and buy into Superman being the greatest hero ever too quickly.
