Query: Hard Candy

I knew this film would be brutal, but the level of edge of your seat frightening was unexpected. Wow, Ellen Page was this normal, cheerful kid one minute and a calm quiet, borderline psychopath the next. It was like her level of evil against his, and I couldn't determine who was worse. The movie was well done, but very dark and won't be for everyone.
