I agree with The Clown Prince, a Batman movie has to be a gritty crime drama but in the context of the DCEU we should also get some of the most fantastic elements of the the superhero world.
Hopefully it will be the best of both worlds, I trust Affleck.
I've been a Batman fan since the late 70's / early 80's, I've liked every comic book iteration but was less enthusiastic about the movie versions.
I disliked the 89 and 90's movies (no offense to the many fans), I loved the Nolan films but Batffleck is the first time I really feel like I'm seeing Batman on film.
I credit Snyder for that, he gets a lot of crap from critics and some fans but his stuff looks like it jumped straight out of a comic book.
