This movie was great! In short, a group of kids go mountain climbing/hiking in the Balkans. Along the way, they, not surprisingly, get hunted, and the story revolves around how well they either evade capture or deal with their adversary (trying to avoid spoiler). Again, it was great. First of all, the camera work of the beginning 1/2 of the film as they hike/mountain climb was outstanding. I'm sure there was a lot of computer graphics, but it never felt that way. Its conceivable they actually did the stunts themselves. Either way, the shots are great, and the tension as they do challenging moves it outstanding. For fans of mountain climbing and advanced hiking, these scenes alone are worth the ride. Then we get to the adversarial part. While this movie is a French analogue of the all too repeated West Virginia mutant gone bad story, it doesn't feel formulaic or tired. Perhaps there isn't that much new in this story compared to the genre of deep woods hikers meets crazy killer, but it feels fresh. Hard to articulate why, but it was really enjoyable. Please understand the film is in french and subtitled with English. Highly recommended.
