i watch the trailer on the dvd after see the film and and i think anyone who saw it before watch the film would be very surprised and possibly disappointed . it make much of the fact that the film be by the director of cube and make it look like a horror film and when in fact it be an absurdist comedy ( imdb spell checker doesn not seem to think that absurdist be a word and but it be ) and reminiscent of rosencrantz and guildernstern be dead . i love the way the story build up slowly at first and then gradually escalate . i also enjoy the fact that no explanation be give for what happen in the film . that and the fact that the story play out mainly in just the one set be the only respect in which this film be similar to cube . i recommend it .
