I think I'm one of the few here who isn't completely on board with how Batman looks in this film.
The actual suit itself, looks great, especially in this shot
However, the gigantic build that they're going for - I personally don't like how bulky he is. It worked fine for the aesthetic of Dark Knight Returns because nearly everyone had that giant proportioned build, but as far as it looks outside of it, I think he looks too big.
If he had a build like Clark does, it would be perfect IMO.
Who knows, might look alot better in the film (that poster lighting makes it look not as great in comparison to the black and white photo.)
