I like the choice of Snyder. I loved "Watchmen" and "300" and even "Legend of the Guardians" is basically "300 with animated owls".
Here's the thing about Snyder: he's not afraid to get down-and-dirty. He shows not only the human side of his characters (their frailties, their bad decisions, their egos) he also shows the blood and the aftereffects. This is what I'd like to see, especially where Superman is concerned. Sure, the last film was a bit too "emo", but I liked seeing Routh showing more sides to the character... otherwise, what IS the character? The Superman as we know him from comics and cartoons is basically an emotion-less caricature like Dick Tracy. And I like the way "Smallville" explores how the character struggled with growing up, having human parents, having human issues such as love and figuring out his direction, having to deal with his real father, etc.,. Hopefully Snyder will basically take that kind of stuff and translate it to an adult Superman. Think about it: if you were almost omnipotent, how WOULD you rationalize the things you did, keep away from the temptation of overusing your powers for your own purposes or crossing the moral line the way some of the characters in "Watchmen" did?
