If you want to watch a movie that you can immediately fall asleep to once the credits start rolling then skip this one. The first time I watched it, I was in the military stationed in South Korea, sure I didn't have much else to do but immediately after the credits appeared, I walked to my best friends room and made him watch it with me. Before we knew it we had 6 people in my room rewatching it just so maybe one of us could figure out the ending. It may start a little slow but as soon as you realize what's going on you'll be sucked in and calling your friends to help you piece the story together. If you like psychological thrillers and something to make your brain smile then you'll love this! Great acting, great story, great everything! If we were friends this would be the first movie I tell you to watch!
