Regarding Malick- Parker, I don't think that anyone's saying that anything in this trailer is anything near as good as Malick, just that they can spot an influence. And that influence is there, but noting and appreciating it isn't the same as a comparative value judgment. And there is a Malickian vibe in this trailer, but it's not just like Malick, it's influenced by what he's contributed to the cinematic lexicon to evoke a certain dramatic energy and feel. Saying, "Oh, cool, that's kind of like Malick," is coming up because it's the most obvious touchstone. If anyone is putting Snyder on the same level as Malick, just in terms of basic aesthetics, that person is insane.
Some thoughts from someone who's way too into Superman:
1) I don't mind the seriousness. Serious doesn't necessarily equal dour, which is what Returns was in its worst moments. This doesn't feel dour so far. Besides, there have always been notes of melancholy to the character. It's one of the reasons why he resonates. One of the things that the Superman story is about is living with grief in a world that doesn't quite understand it anymore, but being able to live a good and happy life despite that.
2) I like the idea of duelin' teasers more than the actual execution, but I like what it seems to hint at with regards to their tack with the origin. In the Donner film, the "Superman identity" is something basically foisted upon Kal-El/Clark Kent by Jor-El, so he never really "owns it" in that film, which never sat quite right with me. They seem to be setting up a conflict between the desires of Jor-El and Pa Kent, with the resulting invention of Superman being Clark/Kal's distillation of both of their lessons. Which is something that I like about the current (sometimes spotty) Action Comics run: Superman is his own invention and his own man, which I think rings truer to the character. Here's hoping this movie follows a similar route.
I don't know that I'm completely sold, but I'm at least cautiously optimistic at this point. We'll see what happens.
