It looks... fine?
I dont know, Snyder's issue has never been creating cool looking moments, so its hard to judge any of his work on them. Man of Steel had an incredible trailer, sucked. BvS had a cool trailer, sucked harder. Even Suicide Squad looked good before you sat down and it had to be a film.
I liked Aquaman riding the Batmobile, that looked enjoyably daft. They actually said "Aquaman" which I guess is a plus. To be honest he looks about the best thing in it.
Cyborg looks like a decepticon fucked one of the Iron Man suits, horrendously bad.
Flash and Wonder Woman look ok, Batman is there. I just have very little confidence that it can deliver on an actual story, so its hard to be excited or hateful of it yet. Still very dark and grey though, but its Snyder so I cant exactly be shocked by that.
