Just saw it. It's amazing. Here are the positives.
Hans Zimmer's score. Probably the best music I've heard in any superhero movie, up there with dark knight.
Action sequences are fluid and intense, long winded and dynamic, they are never boring and you can see everything.
CGI was great. Doomsday was amazing looking, especially when batman was flying overhead.
Lex Luther has his charm and I see where they are going with him, an eccentric genius that is 'the joker,' in terms of crazy levels. Just more manipulative.
The story was actually pretty easy to follow. But it had continuity problems with tying everything together.
Dialogue was good at times.
negatives are that the story does feel disjointed and does have continuity issues and because of this, everyone has a sort of sixth sense to determine what everyone else is doing.
Some parts were cheesy.
Aquaman and the insertion of unnecessary characters to join in, in future installments. They felt shoehorned in.
Lex Luthor isn't the traditional, cold calculating type, he does feel like he's unrelenting and hyper aggressive without understanding the consequences of his actions. But that is most likely due to his age in the film.
The ending pissed everyone off because someone died...
People complaining about Batman / Superman killing people is ridiculous. It's a realistic outlook on these characters. Of course, Batman is going to use his miniguns on his batcopter when other people in apc's with cannons are shooting at him. Also, he's just a mortal man in a suit, facing dozens of guys with armed machine guns. There will be casualties... for his sake.
