It's no definitive masterpiece but it's damn close.

Good films always raise compelling questions, whether the format is fiction or documentary fact.

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.

TERRITORIAL BEHAVIOUR is a simple found footage-style horror film in the style of THE BLAIR WITCH PROJECT in that the terrors are all unseen and of the psychological variety. The film is in essence the video diary of a sole hunter as he ventures into the Montana woods and soon finds himself assailed by both vengeful hunters and a supernatural force.First things first: it turns out that this is an Irish production, and I had no idea until checking online. It's completely convincing as an American film, the Irish woods stand in well for Montana, and Ronan Murphy nails his accent perfectly. In terms of authenticity this gets a ten out of ten.Otherwise, it's rather sluggish and really suffers from a lack of incident; there's only so much of one guy talking into a camera that a viewer can take. It's lucky that the landscapes are picturesque. There is some atmosphere built up along the way but the ending is too abrupt and there's no real sense of menace, either; things never get nasty enough for this viewer.
