Quoted from vid1900:
That movie is so dumb.
If Superman could simply fly around a planet so fast that he could turn time backwards, then time travel would be an easy way to fix ANY problem.
Why did the other **supermen** not just fly around Krypton and save that planet too?

There are no other supermen.
Kryptonians seed our sun for that.
Everyone knows that!!! DUH!!!
