Ugh, I'm so sick of origin stories. Everyone knows Superman's origin. Get to the action, that's what he's for dammit!
The only time I enjoyed a protracted retelling of an origin was in Batman Begins because it was so amazingly well done and was a globe trotting action story with ninjas
I can only pray the movie OPENS with Clark leaving Smallville to become Supes for the first time. And that it has a villain as physically powerful as he is. And lots of huge action scenes.
