It was a really great movie that kept you guessing the whole time. Blake did a great job playing the crazy person role.

I really enjoyed this movie. It kept you guessing throughout with lots of twists and turns. I really like Blake Lively's character. The ending was a little slow. I would definately recommend this movie

I enjoyed the suspense plus the humor was a spot on; BUT the language was a bit too much for me.

unpredictable. full of suspense
