I generally like movies where a group of strangers are isolated and pitted against each other because they offer a portrayal of Darwinism at work. I like the mystery of it. Who has what it takes to survive and to what lengths are they willing to go to make it happen. This could have been interesting even though it's not an original concept. What ruined it for me was the end of the film, because the audience is deprived of any explanation about the point of it all. Why did all this just happen? Was there a purpose? What the heck was the purpose? I have no idea. I would advise skipping this one unless you literally have nothing better to do with your time.
