I'm a huge Superman fan, and that's a concept that is reinvented time and time again, often successfully. As each new variation arrives, we are free to accept or reject them as either: a) true to the core concept of Superman, b) quality entertainment in their own right, or c) both.
As am I, see the avatar and sig, and that is exactly the approach I take with both Superman and Trek.
In fact, I've come to approach Superman with the attitude that if it has the basics and the story is good, I don't care if everything fits within a "continuity." It's the same attitude that I've applied to Trek since Enterprise came out. If it's good, it's good. If it's bad, it's Voyager.
Hell, I have my favorite iteration of Superman (well, a few). I have my favorite iteration of Trek-- the original series, hands down. But if there's a good story that features those characters and that setting, that's all I need. I don't care if it matches 100% to what has come before.
I've said it once and I'll say it again... screw canon!
