I agree with everything Rorschach just said about Superman: The Movie and MOS, but the whole spin around the world turn back time bit, while it may not make sense in real life, it makes perfect sense emotionally and that's why it works in the movie. Plus, if you just let go of "well how would this work?", it really is an awesome scene, I always thought it was really cool, one of my favorite moments in a superhero movie - simply fantastic.

And then the follow up/epilogue to it is great.
Except for the Jesus analogy stuff, they really get Superman right in that movie. Combine the story of that and special FX of MOS and you have a perfect Superman movie (and, truthfully, some of the 70s special effects in that film hold up really well). I remember being excited when I saw the MOS trailer 3 (still waiting on that movie) when I saw the shot of Superman flying over the dessert and how it reminded me of the missile chase scene from Superman: The Movie, I thought "what must he be doing at that part? I hope it's some intense bit that pertains to the story, like some chase, and him running out of time" or something like that...maybe chasing Zod over the canyons... that would have been great...
