About the ending...

Ok i know there's some other topics about this and I apolize if you feel this isn't necesary... anyway:

First of all I have to say that this movie is genious, people see it as a movie that tries to be funny or witty but I think it just tries to be wrong and it's amazing how well it acomplishes that.

About the ending, I think she is crying because she is sad, not because everything wasn't worth it but because something didn't go as planned. The arab girl dieing, she said that wasn't supposed to happen. I think she wanted to be like the kid who shooted ppl at the school and how in the end she watches him and sees how he isn't sad or regrets anything because everything went perfect. Yet she sees herself in the show, she got back at her friend, but the arab girl died. (aka something that wasn't in her plans)

I do think that it is hard to let the film end in such a simple manner as "she simply regrets everything" due to the great work everyone did at making Kimberly some sort of invincible subject. Or it could also be about she comparing her in the show (as a 1 time thing) in competition to making the arab girl more famous than her.
