I'm surprised this topic hasn't seen more action after the outpouring of outstanding positive reviews from critics.
I've been rewatching the MCU films to lead into Civil War, and I have to say, they do a stellar job of making these characters have actual progression. All of their stances in Civil War seem to make sense going into the movie - and from what I hear, they're all taken to their logical conclusion.
I feel that this will absolutely show up Batman v. Superman. Better acting, screenplay, action, characters, and overall execution.
