I think this looks quite good, but then I seem to be in the minority of folks who really liked Man of Steel. I hate how every superhero movie now trends to be measured against The Avengers, which I actually didn't particularly like. I'm excited to see how this one comes out.
I really liked Man Of Steel too. Only just saw it for the first time a couple of weeks ago. I really don't get the hate for it. The story was good, and it had at least one layer of subtext to it, which made it interesting and had me thinking for some time after seeing it. And I thought Henry Cavill did a very good job of portraying Superman.
I didn't care much for The Avengers either. It had a very shallow and rather unmemorable plot, with a lot of superheroes behaving badly at times. And Stark acted like an obnoxious smartass most of the time. To me, everything seems so contrived in the Marvel films I have seen. I've only seen three, and part of a fourth though.
I've read speculation regarding Batman v Superman: Dawn Of Justice, that Bruce Wayne gets hold of some of the Kryptonian tech that's left on Earth - such as the wreckage of the Genesis Ship, and World Engine - after the events in Man Of Steel, as well as General Zod's body, in order to bolster his abilities to defeat Superman. I've also heard the story is based in part on Frank Miller's The Dark Knight Returns.
