These 'Cube' movies make me think of Jean-Paul Sartre. Of course. No exit. This is a movie that uses real math, and that means prime numbers. It's a puzzle movie in trying to figure out how not to die a horrible death, and get out. It might be the best of the trilogy because it's original. Also, it has David Hewlitt who was so good in Stargate: Atlantis.
This movie ranks up there with the best of those types of films where characters are stuck in a world they have to figure out and then escape from. It is literally like Stanley Kubrick stylistics, "The Maze Runner" and "Brake" all had a lovechild and this is what came out. Personally, I think it's a brilliant idea and incorporating complex math made it all the more smart. The acting, visuals and story are all solid.
The lack of gore kills feels more like a budgetary concern than an aesthetic one, but it works for focusing the narrative on the characters as they introduce, redeem and deteriorate. An ending that I found to be slightly too pointlessly mean spirited is the only thing keeping this from a fav.
This is a really good Canadian horror film, with well cast actors, and a fantastically interesting situation. You wake up in a complex of differently coloured cubes, a door on all 6 walls in every cube in the complex. Some rooms are safe, some are booby trapped.
Definitely an interesting and quirky idea, but the end result needed more polishing, since now it seems very one-dimensional. The acting is poor, like others have noted. I mean, you don't need a big budget to get good actors, who don't behave like they're in a bad B-movie (I'm looking at the one guy in particular).
