Between the character development, sound track and awkwardness behind certain characters, all of it comes together amazingly to add to the eeriness and suspense of the movie. With a lot of movies that have ‘a lot going on at once’ its hard to keep track of whats going on...but the plot twist and the way the director sequenced the movie, it just made the events all sit right together. Watching the movie a second time through, you realize how much info the director gave you in the beginning, that appears later on and its an amazing experience watching it even a 3rd or 4th time again.
