I think you can go into some deep territory without losing the wide-spread appeal.  And the Christopher Reeve one is old, it's old and obsolete and while it's got some fun elements to it, you can see through every effect.

I'm all for a different approach, I'm just saying that the number of her films you can take your kids to is getting fewer and fewer... I'm sure it's one of the reasons that the Avengers did so well, kids could watch that easily, it was light, Superman should be light.  Star Trek was one of those great movie series (the old ones) where kids were safe to see it but it would go into deep drama and intellectual territory.
