Hey Gregg, thanks for watching. That's a really interesting point, I'd never considered that it had actually already happened, and when he goes up stairs he's already done it, that'd put a very interesting spin on the conversation he has with the girl.
The main critiscm I have recieved is that it isn't clear enough what he is feeling, and people have struggled to understand what they just saw when the end titles appear, but you seem to have totally grasped the concept. But I like your idea of showing more of the story through emotions, and less through an almost lecture type monologue from the girl at the door.
I do with think with a rather complicated story as it is, playing with a non-linear timeline may have been too confusing, the actual point of the story may have been lost. I'm sure David Lynch would think otherwise though!
Cheers though Gregg, I appreciate your comments.
James
