I saw the movie on Monday, in IMAX 3d and I loved the movie more than I thought I was going to. While I kinda liked MOS, I really did enjoy BvS. Now, it does have ton of flaws. Which all pretty much have been pointed out. Highlighted by Jesse Eisenberg's Lex Luthor. I can appreciate what he was trying to go for, I can even appreciate his commitment to it. However it just didn't work, at all. Now, I don't particularly like him as an actor. So this was already an uphill climb and it just didn't make it. I too loved Ben Affleck as Batman/Bruce Wayne. I think we now have the complete Batman/Bruce Wayne in a single actor. He has supplanted Michael Keaton as the Batman/Bruce Wayne for me, I'm very happy for him to take the title. I also thought that Gal Godot was awesome as Wonder Woman, in her limited role. She has an amazing presence as Wonder Woman, an inner strength that projects through. Now I can't wait for the stand alone Wonder Woman movie.
I think there needed to be another MOS movie between MOS and BvS. I think this Superman needed to be shown earning his places as Superman of this world. You could have had some easter eggs of Batman and Wonder Woman and other stuff, leading into this movie. I'm not sure why we care enough about this Superman to root against or for him in this movie. Other then we know we should based on other Superman history.
