No, it's not.

But I enjoyed this. Theron and Patton Oswalt both gave exceptional performances, the dialogue actually made me look forward to Diablo Cody's next work (and nobody even needed to point out they were talking on a cheeseburger phone) and I was okay with the non-story, mostly for the reasons Zoo outlined. Her character is oddly fascinating, and I actually liked her almost-but-not-quite turn at the end. The world is filled with people like this, and they usually live their lives without self awareness because they will always find people who are willing to enable their awful behavior. Even when it seems like everything in the world has finally hit them smack in the face and told them they need to change, someone will be able to let them bask in the glory of their own assholishness and let them know it's okay.

And nobody actually calls it the Minny Apple.
