So the problem here is that the movie is a complete dog.
There are 101 reasons why the film is terrible but the overarching blame must rest on the ‘found footage’ gimmick that is applied in such a slip-shod fashion that whenever it is highlighted it knocks you out of the film as you wonder ‘who was holding that camera?’, ‘how are we watching footage from that camera when it just got sucked into a fire tornado?’ or ‘if I was just about to drown would I really be filming a video diary?’ etc.
The word ‘conceit’ looms large here in big flashing lights but, perversely, this is the only movie I’ve watched in the past couple of years where I kept wishing it was in 3D… because if ever something should have been a fairground ride it was this one.
