Say what you will about SR's flaws, if Superman: the Movie made me believe a man could fly, Returns made me believe a man could fly faster than a speeding bullet.
I'm not saying Superman Returns was a bad movie. In fact, I saw it twice. I'm just saying I don't understand if our technology for effects is supposed to be better today then 10-20 years ago then how come the flying seems more "real" then the Chris Reeve films and Lois & Clark. That's really all I was disappointed with SR. I can still watch the Chris Reeve films and say "wow" to the flying, but with SR, it's just "meh".
