Hard Candy (2005)
If you haven’t seen this one, you really should. This is Ellen Page’s breakout role and it turns the story of Red Riding Hood on it’s head, into a feminist parable. Page plays a girl who lures a supposed pedophile, and enacts her vigilante revenge on him.
This film, directed by David Slade, turns the table on the torture porn subgenere and makes this film into a gleeful story of revenge and suspense, worthy of Hitchcock.
