So this film is apparently based on a real life story of nine Russian hikers who mysteriously all died in the Russian Ural Mountains in the 1950s. Something forced them out of their tents in the early hours and they froze to death. I was intrigued by the title of the film, the true story was something new to me completely.
This film follows a group of US students who are out to make a film exploring the incident. It's an interesting story and is told through TV reports and found footage.
The acting is generally good and believable. It's a solid film and builds up to the climax well. I like the twist at the end of the story. The idea in the film is scary rather than the film itself. I did enjoy it, having said that.
