Like WTF!? The ending was pretty vague anyway. You get to the surface with things blowing up. Cut to music. Why is there even a need to change to and re-capture?
Why is there this growing trend of writers going back and reworking their story? It's not like there's a Homer's Odyssey (revised edition). I'm sick of it. Let it sit. Write a NEW story.
