ENDING: Which one is it?? (SPOILER obviously!)
I didn't like the movie. As far as the pre-ENDING it was obvious that it was the girl and not Adam.
BUT for the actual ENDING (the jail scene) I think there are 2 possibilities:
(1) It was all in his imagination. He is a convicted felon who wrote a script maybe based on his experience (his crimes).
OR
(2) The whole movie actually happened, and he is wrongfully accused for Adam's and possibly all the other murders but he couldn't prove his innocence.
Your thoughts?
