It was crazy! The suspense held me the entire movie but never offered relief until the very last scene. It was like a never-ending ascension to the top of a Rollercoaster that never came back down. I was nervous and stressed the whole time, waiting for something to happen to one of the main characters and nothing ever happened to them - which is good, I suppose lol. I still feel stressed even now that the film is over because it never felt like there was a resolution within the film, even though it kind of was. I don't know. It was strange but I think it did it's job.
