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?
I was 12 years old when Independence Day came out and it was just about the greatest thing I had ever seen. I watched it again in college and it totally held up. It's absolutely one of the greatest blockbuster sci-fi/action/adventure movies ever made.
