Have you seen all three of the movies in the Cube trilogy? I've only seen the first and the third, and I think they were both cool, even if they were rather gorey at some parts. My favourite so far was the first, though one of the actresses in the third is known for voicing someone in Sailor Moon ;D
In the first Cube movie, several people end up in this maze of perfectly cube-shaped rooms, and some of them have deadly and even gruesome traps. They have to figure out which ones have traps, and find out how to get out of the place, before they die from hunger, thirst, or traps. Only one makes it out alive in the first movie. In the second, it's more flashy and has a somewhat different plot, and only one makes it out, though even she dies. And in the third, a prequal, it shows more of the outside workings of the system of cubes, but even that one doesn't elaborate on everything.
