Too late, I saw Hypercube. And Cube: Zero.

You're right. They weren't nearly as cool. Hypercube was interesting because I've always been interested in a 4,5,or 6 dimension universe. My wife was thoroughly unimpressed since she had no idea what they were talking about. Cube zero was unbelieveably bad. Total waste of time.

But I thought the first one was very very cool. Well done, makes you think, and very very different. Not bad for a budget of $300k. And shot totally in 1 room.
