You know how most thrillers have plenty of dull scenes where the suspense stops and you get kinda bored? This one doesn't have that. The suspense is kept from beginning to end, which makes it close to impossible to stop halfways. The acting is great and believable, and the story isn't obvious at all; more like the opposite. It's one of those stories where guessing the ending is close to impossible! The downside to this movie, in my opinion, is that it kinda has two stories going at once and they don't tie together in the end. It leaves alot of questions and you end up feeling that alot of things just weren't explained. The twist feels more random than anything else. Yet because of the suspense and the great acting, I would recommend others to watch this movie.
