I never stop watching a film once I have started despite how bad it is, but this almost became a first. It was so dull and characterless, I didn't care about anybody in it and so couldn't care for the film. The story was non-existent, the script was awful. How many times can you use the words 'door' and 'camera' in one movie? The camera work was nauseating. The horror element was meaningless and did not make sense. This would have worked better in my opinion as a straight forward violent thriller but only if there had been better characters and we'd been given someone to care about.

Honestly I would not waste your time watching this. I wish I hadn't.

In some ways this could be the most realistic found-footage film of all that I have seen – in that it's often impossible to work out what's going on. Equally, the depictions of the group of teenagers getting drunk and swapping embarrassing stories is immediately tiresome.

As the story goes, a man (Eoin Macken, who also writes, produces and directs) gains possession of a second hand camcorder, and on it he finds footage that appears to depict the final hours spent by a group of currently missing Irish girls. Spending an evening in an abandoned warehouse isn't everyone's idea of a good way to celebrate a birthday, and tempers are frayed from the outset. These are flawed people. When they are attacked by vagrants, however, it comes as a relief the camera-work is shaky and obfuscates the resulting raw abuse.

When it is revealed there is a bigger, supernatural threat at large, the pace of the film slows. We are treated to quite slow scenes involving the characters reacting to barely glimpsed creatures not dissimilar to those in 'The Descent', and some unexplained sounds of a baby crying.

The found footage formula ends when 'The Man' has reached the finale and we return to more coherent, slick direction of regular film-making for what I feel is the least convincing part of the story. Having seen a group apparently slaughtered by demonic forces in a location that is familiar, would you then take it upon yourself to investigate that very area, unarmed and alone? Because I wouldn't. Yet that is exactly what the man does. Would he not hand over the webcam to the police? I justify his actions in this way: we saw him pawn his ring for cash. Perhaps he has a drug habit and is reticent to contact the law? I wouldn't suggest for a moment that people who pawn their goods are addicts, but it's the only reason I can imagine he doesn't contact professionals to deal with this. Much as this lapse of logic happens in horror films, I found it difficult to get past here, which mars an otherwise very effective feature.
