I wanted to get a point across that many of us don't think about, which is where we all came from. We started as children adoring these characters. For me, Batman and Superman were such key heroes during my childhood and it was a real treat to be able to enjoy so much of what was out there without my parents really ever worrying about my heroes in films being too much that I would have to wait til being a teenager to watch some of this stuff.
What I have really liked about what has been done in the Marvel films (for me, and please don't accuse of Marvel bias because I LOVE both sides) is that they seem to do a pretty good job touching a pretty broad age range fan base to where kids are getting something they love out of their heroes, while adults are getting some content they enjoy out of them, and keeping a good balance and awareness that LOTS of people of all ages love these heroes and are doing what they can to not single out anyone.
I definitely see some good stuff in this new trailer for Bats vs. Supes, but there's just a heart that is really lacking that I cannot connect with, especially Superman. And Batman I have no idea how that's going to go, but for right now I feel no connection to him just from lack of yet-to-be-seen character development of Affleck's Wayne/Batman role, which will have more of an opinion post-release.
Right now I still don't quite feel like I know Clark well, nor do I feel like I completely trust him the way I have seen Christopher Reeve. Those films are very old now, but one thing I have to credit to Reeve is man, you look at him and the way he just interacts with people, you just seem to know everything's going to be okay. Cavill's look has a real edge and thing about him that I don't think I would feel comfortable approaching him. Superman is supposed to be the epitome of hope.
Oh and Wonder Woman shouldn't even be in there as far as I'm concerned right now. She should have her own origin film first.
