Even though it's been done in different forms in other movies, this one actually presented more human behavior than gore. Of course the first movies comes to mind are the "Saw" series but there wasn't the challenges or choices, simply survival and human nature. While the people were all abducted by an obviously disturbed person, it could have as easily been about people stranded or trapped from natural causes or by accident. It did of course include the option of cannibalism and how long one could sustain from going that far, if indeed one would have to. It could have been way more gory and graphic but that wasn't the movie's intension. The acting wasn't bad and it didn't look low budget. The best part is that the story ended and didn't leave any opening for endless sequels or prequels, you have to give it credit for just that.
