The theme of the film is certainly an interesting, controversial and ambivalent. However, with the implementation of the film I had some problems, which has led to me really emotional issue has left very cold here. When "Pound Blair Witch Project", the film is being touted on the cover or in the blurb. Plus the endorsement "Thriller". Unfortunately, both references are the film does not really do it justice.
Maybe it was the combination of documentation and Imitation Thriller, the person did not work for me. I have the movie via Prime Instant Video looked, so I did not have the opportunity to watch the film in its original language. The German Synchro always looks very fake and artificial. Right at the beginning to tell the "victim" in retrospect, what has happened to them. This has two major drawbacks that are not good the film, even if the approach was interesting. On the one hand we know so from the beginning, who all survived or whether there are victims - a stress killer. On the other hand, the narrative style (victims express themselves in front of the camera - exactly as in a documentary with witnesses) the film neatly in pace and rips a constantly from happening.
Maybe the type of film other like better. For myself it was nothing, though I "other" films else like very much and am just as happy to films remotely of the "mainstream" (to be value-free meant here) inlets.
