This could have been a great film, and i thought it was going to be after a good first half, but then the 2nd half went and ruined everything, very very disappointing/terrible second half in my opinion.

Just awesome, one of my favourite movies, and HIGHLY underrated! Despite liking horrors, I don't find many of them scary, but this one was sssscary man! It probably didn't help that the first time I saw it, I was a little high. Had no idea what it was about going in to watch at the cimema, but was the only decent movie on at the time. Like chiew said, gave me the heeby jeebies and then some! If you like your horrors a little less graphic, and a little more physiological, give this a whirl... but preferable NOT while you are high, although it's just as scary sober, as I've found after watching it several times since, something I rarely do with any movie.

One of the weirdest and creepiest movies I've seen in a long time! Bit scared to go to bed now :')

I don't get it...this movie could have been so great if they didn't screw up the second half. Wtf was that?

Clearly it took some inspiration from Hellraiser's series, but still a fast-paced horror sci-fi, enjoyable on its own. Also Richard T. Jones made me laugh much more than it should.
