Re: Should this have a Batman Villian and if so who should it be?
Joker and Lex were the first villains that came to everyone's minds when this film was announced, and that's not necessarily a bad thing to pick the most obvious villains.
I'm allll for that rumor of Lex and Joker with some creature (hopefully Bizarro)
I think this is the perfect place to reintroduce Joker. If he's introduced in the solo Batfleck films, it'll inevitably be compared to The Dark Knight and Heath. But if he's introduced in BvS, there's a little less pressure because he's being introduced in a completely new and fresh way
