This film is about 80% "found footage" so if Blair-Witch-like puts you off, probably not for you. Shot on video, it has the feeling of low- budget, but much better than many low-budget horrors.
Firstly, although the acting amongst the females is a little too 'screamy' they're in quite an unpleasant situation almost from the start, so it's understandable. The script is fairly realistic, and the antagonists that arrive are suitably menacing and unpleasant - this isn't a film full of nice people, and it's definitely worth its rating, more for the scenarios, than for any graphic blood-letting.
The story itself is fairly interesting, and the suspense quite gripping. It feels as though there's a prequel story to be told which would hold my attention.
Not a stand-out movie, but evidently a "one-man" show (written, directed, produced by same guy) that is far better than similar ones in this genre, and you definitely feel it has merit.
There are more than a few 'huh?' moments in terms of what the main characters do, but there is much left untold - and I feel it's okay for not every aspect of the events to be tidied up and given a neat explanation.
In summary, much better than I expected. Professional looking, and well executed. A film-maker to encourage and look out for.
