Although this is a plot we've all seen many times before in previous films, this movie harks back to the style of the '80's horror film and is surprisingly entertaining. With an interesting setting and cast, it brings a modern twist to the concept of people being trapped and stalked. Although not really very frightening (more of a thriller really, with little blood and gore) it's a film that keeps you on the edge of your seat and contains some shocking twists and turns as the narrative progresses. The finale is well done and doesn't leave unanswered questions for the viewer, really making you think about the fate of the characters and the choices they made.
