Kind of a no-win here. The Superman outfit looks goofy if worn in real life, but if they changed it the diehard fans would be flipping out. It looks ok, although I think the S should be bigger. In the end, it's still a guy who wears red panties over his tights.
After reading through the Death & Return of Superman comics recently, I keep thinking the costume of the Eradicator would have worked quite well here. If they jazzed up Batman's uniform in the movies, why not Supermans?
Disney is so stupid. Except the sad thing is, they aren't. This'll make money, probably almost as much as a Pixar production would, since most of the paying public holds more stock in the Disney name than the one with the little hopping lamp.
