Okay, first off, Superman WITH A BEARD? It was established from back in the 40's that Superman didn't have facial hair because it didn't grow under Earth's yellow sun, the same as the hair on his head, in order to solve the problem of "What does Superman use to cut his super strong hair?" I guess that the people at DC just didn't want to come up with any better an answer than that. Anyhow, if he DOES have a beard in the movie, the question becomes valid again. Bullets can't penetrate his skin, knives can't cut his flesh, but somehow scissors can cut his hair? Doesn't make a bit of sense to me.
In the comics, Superman would shave using his heat vision and a mirror made from a part of his space-craft. It always made me wonder if he shaved his man-garden using the same method? =/
And, once more I have to say, this actor just plain doesn't look like Superman to me. Superman is supposed to be ruggedly handsome, not boyishly pretty.
I will say this, at least Cavill looks like a MAN rather than some teen idol. There seems to be a few shots in that trailer where he's channelling Hugh Jackman's Wolverine.
One of the problems with Superman is that he is (almost) PERFECT. No human actor is ever going to be able to live up to that expectation physically. Superman also has the misfortune of being one the few superheros who doesn't wear a mask "“ you see his face all the time. It's a far more touchy subject for comic books fans than it is for superheros like Batman, Iron Man and Spider-Man "“ characters whose looks come down to design choices rather than physical appearance.
The best way to look at movie adaptations is to remind yourself that they are just interpretations.
I don't think that there has yet been a definitive Batman movie. That doesn't mean I didn't enjoy the hell out of The Dark Knight, its just that it wasn't MY idea of what Batman should be. I think Tim Burton came closest with his 1989 version.
You can't please all of the people all of time. But speaking as a miserable cynic, I'm genuinely surprised at how great this new Superman movie looks.
