Well, here goes another opinion against the TexAgs collective. I actually really enjoyed that movie, but it took me several viewings to get to that point. It is not a perfect movie by any stretch, as already noted, but like other movies the collective finds objectionable, it gets way too much hate.
It was a dark movie. As noted in the previous post, Batman is ticked that Superman brought extraterrestrials to earth and then brought down much of Metropolis in defeating General Zod. The movie is a slow build, true. Henry Cavill looks like Superman. I was initially aghast at Affleck's casting as Bruce Wayne/Batman, but after seeing him in the cape, I felt like he nailed the idea of a brooding, vengeful Batman who has faced much loss in his life (as evidenced by the quick shot of what was supposed to be Robin's outfit, I think). I really liked Jeremy Irons (Hans Gruber's brother from Die Hard with a Vengeance) as Alfred. Wonder Woman was fantastic, although the seemingly endless previews over the seeming years waiting for this movie ruined what should have been a HELL YEAH moment.
I don't really know how to tread here, since you've indicated you only watched 1.5 hours, so I will spoiler tag the following for you. Read if you care, or not. Many here absolutely hated Doomsday in this movie. I did, too - at least initially. But upon many subsequent viewings, I found myself drawn to that entire part of the movie. The capture of Clark's earth mom, the challenge delivered to Superman to kill Batman, and then the birth of Doomsday - followed by the throw-down between Superman and Doomsday, with a booming, brooding score by Hans Zimmer, just kept me on a wierd emotional high that probably goes way back to when I was 3-4 years old and my grandmother would take me to the 7-11 behind her house to get a Slurpee, which often came in a big plastic cup adorned with DC characters like Batman and Superman, so the chance to get to see these characters on the big screen together was a big deal for me. Yikes, what a crappy run-on run-on run-on sentence there.
This movie laid the foundation for Justice League, which had a couple of decent moments but was largely garbage. And that's too bad, because I believe there is an audience for a well-done DC series. Maybe not Avengers box office numbers, but certainly profitable and also well done. DC/Warners made a huge mistake in not taking the time to build up their movies like Marvel did, so that when the time came for Justice League, the movie-going world would be ready for it. They also made a mistake with BvS, as this movie should have come much later in the series rather than a quasi Man-of-Steel II.
