I saw this in the theater when it first came out in 2009 and LOVED it. It's a smart, funny and terrifying horror film. It's also a film about female power. The whole cast is great, but Megan Fox is particularly good and deserved way more recognition for this role than she got. Regardless, this film is perfection from start to finish and one of my all-time favorites. If you're a fan of horror classics, this is a must see. Viewer beware: it is graphic at times, so not for the faint of heart. But it's a bloody good time!
