Half the film was watching "normal teenagers" before the story actually started going and once it did it re used the same story, just with different people.
It was predictable and the scariest thing about it was how long I actually sat there and forced myself to watch it.
It was random at the end, seeming like the directors had no idea what to do so they threw in something random.
The only reason I'm giving 2 stars is I like the idea right at the end,but not giving spoilers.
