I just watched it last week on Amazon instant. I LOVED this movie. Some parts were so unbearably painful and infuriating and others actually had me laughing out loud. I had no idea where this movie was going, and was a smidge let down with the outcome as I thought the ending lacked the ballsiness of everything that had happened earlier in the film.
Other than, that, I cannot recommend this movie enough.
"IMDB: Where 14 year olds can pretend to be jaded, 40 year old movie critics."
I didn't get the ending. It really lost steam for me with the ending, and kind of showed that her being wild, out-of-control and presumably using drugs with her new friends was a positive conclusion. Also felt that the whole "finding a new man to replace the old one" theme for an ending was unsatisfying.
