OK, I have a question about the movie:
in the opening sequence, he is in the plane and all the other folks are freaking out because the plane is crashing. He's oblivious.
Is it
a) a dream sequence that explains that he is on anti-depressants and he's lost all emotions;
b) the last chronological event in the story, when he goes back to LA but because he is in love with the Portman character, he doesn't care that the plane is crashing, or
c) some other thing.
I'm not really satisfied with a) because I'm not sure that you are as "flat" in your dreams as in your life when you're on anti-depressants. Besided, there's that kissing scene when they're playing spin the bottle (what a bunch of losers...) to show that he's lost most of his will to live, so what would be the point of this scene?
But I'm also not satisfied with b) because heck, wouldn't he be at least a little unhappy about having lost the love of his life?
So it's overrated for me because I can't make the first scene fit with the story.
