They also left open Parkman's fate.
Also was that lady in the future wiped out or stranded when the future was changed?
I am hoping stranded as that would be worse IMO.
I am going to say stranded.
However, I did have ONE major problem with the ending. Instead of Noah sacrficing himself, and the woman being left in the future, they should have popped her in-between the two kids and used her as the focal-point.
But, I understand the way it was written. More emotional story.
