In a desperate attempt to look on the brightside, Piper Cochrane is hot in a milf-ish way.
Very crude, and all around disturbing.
I say "for the most part" because as much as I love blood, guts and gore, I really can't stand rape. The rape bit was important to the character and it was brief.
Above all the movie was just well written and had little spikes of funny, like a humorous porcupine.
