You know what I find kind of odd though? The amount of people who were still cheerleading this movie all the way, even though so much of what people are now complaining about was readily apparent from the trailers (especially the first two).
Dark and gloomy tone? Batman blowing up folks in the Bat-wing? Superman looking all mopey and conflicted about being a savior? The list goes on, but it was all in the trailers.
I can understand having issues with the pacing/editing, and the way the Batman/Superman conflict was handled in the story but all the direction of the characterization and tone have been pretty crystal clear to me since the first teaser dropped. I guess as fans we can't help but hope for the best, especially for a movie of this historic magnitude. I know a lot of faith was put into Terrio, but to me this movie really feels like Snyder's baby through and through. Don't forget, originally the story was something he and Goyer came up with together. I'm sure he was very involved in the development of the script. His sensibilities are all over the story, not just the visuals. This movie is pure Zack Snyder.
I've been telling my friends when they ask me about BvS, "It has some big issues, but if you loved MoS and Watchmen, there's a good chance you'll enjoy BvS."
I am not a huge fan of either of those films though, so my enjoyment of BvS was about on par, maybe a bit more just for if only for the novelty of seeing Batfleck and Wonder Woman for the first time.
