Excision (18)

This body-horror comedy flies right out of left field to smack us in the chops. AnnaLynne McCord plays acned teen oddball Pauline, oppressed by a priggish mum (Traci Lords) and determined to be a surgeon so that she might save her younger sister from cystic fibrosis.

Pauline's dream life conjures horrific fantasies of bloody dismemberment, though so far she's only practised her cutting technique on dead birds...

Two major surprises are 1) that it's very funny in a sick, overheated kind of way, and 2) that a film so obsessed with menstruation and virginal angst should be written by a man rather than a woman. Take a bow, Richard Bates, Jr, you have successfully freaked us out.
