Here's my (mostly positive) review:
Just saw the movie. A few things:
1 - The critics are right. There are some flaws in the film. The most notable is the editing and pacing. You can tell that the 3 hr version is going to be the full story. The film definitely feels trimmed. However, while this is bad enough to be noticeable in places, it was not bad enough to detract from the film for me.
2 - The acting performances and the themes of the film are powerful and well executed. I had long conversations about the film with my father after we saw it together. Its not a generic summer blockbuster - there's a lot here that's meaningful.
3 - BvS is a better story than MOS, but MOS was perhaps better executed.
4 - This is not like "Watchmen." Don't listen to that critique. The film is dark, but not that dark. I'd say its about as dark as The Dark Knight. The film is definitely not nihilistic like Watchmen and there are plenty of beautiful and heroic moments. The ending is very redemptive and hopeful in nature.
5 - The cinematography is beautiful, the special effects are as good or better than what we saw in MOS. My worries about Doomsday after seeing him in the trailer were absolved by the film - he looks great here and in context he really works.
6 - There is indeed humor in the film. I wouldn't say it works as well as in the Marvel films, because something is off about the comedic timing. Another editing problem. However, there was one comedic beat in the finale that had my whole theatre laughing.
7 - Speaking of the audience, my theatre was packed. There were four moments of audience response at the appropriate times. I was surprised because the last time I've seen an audience that "into" the film was during the Fellowship of the Ring. Here's the parts where they responded (spoiler tags):
[BLACKOUT]When the bomb is about to go off in the senate hearing[/BLACKOUT], the audience murmured uncomfortably and one guy across the aisle said loudly to his buddy "something bad is going to happen."
[BLACKOUT]When Batman saved Martha and Martha made her wisecrack[/BLACKOUT], the audience laughed. And by the audience, I mean everyone. That moment landed very well.
[BLACKOUT]When Wonder Woman showed up[/BLACKOUT] the audience reacted in various ways. Some people oohed, someone in the back said "hell yeah" which made me laugh.
At the end of the film there was scattered clapping. It wasn't one of those whole theatre clapping moments, but it was more than one group of people. Last time I heard clapping in a theatre was at the end of The Dark Knight Rises, I think.
8 - The critics were wrong. Yeah, yeah, I know - in point #1 I said they were right. But the thing is, the pacing, while flawed, was not as bad as the pacing in Age of Ultron. The film, while dark, was appropriately dark and certainly not humorless or hopeless as I'd been led to believe. I have criticisms of my own about the film (regarding one or two things I won't spoil here), and the film isn't perfect, but it isn't 30% on RT bad. It really doesn't deserve that score.
9 - The moments that need to work really do work. Zack Snyder delivered. This isn't a Nolan film. Its not as clean in execution or as cerebral in atmosphere. But I found it deeply meaningful. There's lots of little things that the film doesn't beat you over the head with. Hopefully you'll catch them. And I found the film more emotionally arresting than any superhero film I've seen in a long time.
So, for what its worth, I loved it. I'm going to wait until my second viewing to decide on a rating, but I'm leaning toward 7/10 at the moment.
