Sure, the comparisons need to be made, but we need to keep in mind that Superman The Movie came out in 1978! At the time, it was one of the most (if not the most) groundbreaking film ever made. The visual effects may seem a bit simplistic today, but at the time - people were wowed back then in a major way! They did what they could with what they had...without CGI.
Superman Returns has a good script, I was actually surprised.
Let's discuss the acting....We won't get into the Marlon Brando thing, 'cause he's sort of in both. Right...anyways...let's move on. Gene Hackman brought a comic element to the role of Lex Luther that Kevin Spacey lacks...don't get me wrong,Spacey is an incredible actor, I just like Gene Hackman's take of the charactor more.
Margo Kidder may be a looney these days, but back in '78, she was da bomb! Which brings us to Brendon Routh vs. Christopher Reeve. I gotta say Routh did a good job, but I think its pretty clear who the REAL Superman is...long live the original. Nonetheless, I am happy to see Superman Returns on the big screen, and it got a much deserved face-lift.
