What I can tell from the trailer.
1) Has the feel of the recent DC movies. It embraces the characters and the weirdness of them, but also is just a little off from doing them right. Like I know who the cast is, but I look at them and say Nope.
2) Highly stylized fight scenes, that are completely not grounded and silly. However, the little action we get in this trailer looks like it could be fun.
3) The raid on the police station being completely none lethal is either going to make or break the movie. If it is high energy and funny, which they seem to be trying to do...then I think it will be great. If it comes across as cheap or just silly, then it is going to hurt.
