Batman vs Superman had potential to be brilliant. I actually LOVED the intro for it. The way they showed another character's perspective of a major event in another movie, really left an impression of me. Like how an event doesn't directly effect you, but the consequences of watching something you have no control or power over at the time, leaves an effect on you. I must say the intro left a lasting impression on me.
I also think Ben Affleck was the Bruce Wayne. take him out of the bat suite, and his stocky appearance is exactly how I've seen him look in comic books. And I loved his grey almost leotard looking suite. It really went back to a more classic batman look.
