The minute this movie started, it had 'cube' written all over it. The high-tech yet raw atmosphere, the lighting, even the camera-work reminded me of it. And obviously this movie was meant to capture a similar type of claustrophobic ambiance.
Now I am totally into Japanese movies (big fan of Takashi Miike), and I love suspense/thriller stuff (I loved the Cube), but this movie was a total bore.. The atmosphere itself was OK, but the acting, the props, the character design, the story, the logics; utter crap. Truly, over half of what happens makes no sense. In addition, the suspense is broken over different events, so it never really builds up. Something happens, and it's resolved... something else happens, and it's resolved.. and none of these things really get to you because they are so incredibly predictable and unnecessary, mixed up with pretentious horror-like cut-scenes to spice things up, which instead ridicule the whole deal even more.. I'm giving it 3 stars for the ambiance and the chicks, but other than that, this movie is not worth your time.. unless you really, really have nothing else to do..
