Yeah I mean don't let my opinion of Man of Steel dissuade you from seeing it, a lot of people loved the movie and I've had conversations with many comic book fans who thought it was one of the best Superman movies.
To me though (and I'm definitely not a comic book reader) the movie took itself far too seriously. From the beginning it's just this very serious movie and nothing about it feels like it's any fun. I'm not saying every superhero movie needs to be Iron Man, lol, but even something serious like Watchmen had its moments of fun.
It never really even tries to make any of the characters likable and unlike Zack Snyder's other movies, which have always looked visually awesome, this movie's dark and gloomy-looking, almost like someone needed to wipe the camera lens. I guess it was the look they were going for but I just didn't find it appealing. There's almost no action through most of it, so it's slow, and then the last hour is non-stop action, and that got old to me pretty quickly. Again, Zack Snyder has shot far better action than this.
I also though some of the dialogue was pretty awful.
So eh. I didn't enjoy it. It was one of those movies where about 5 minutes into it I just knew, "this is going to be one of those movies that I just won't like," and it pretty much turned out to be true.
Anyway. I think that Ben Affleck's a good actor but I also don't know if he has that spark that someone like Bruce Wayne needs. I'm willing to give him the benefit of the doubt though. I just think the choice to do a Batman movie with a new Batman right after a very well-liked Batman trilogy ended is a bad choice. I thought it was a bad choice to reboot Spider-Man so soon too, though at least in that case they gave the series a couple years to take a rest, lol.
