A very weird series I must say...
In my opinion, for a small, independant film with very little funding... it was great. Besides the fact that the Saw movies ripped this series off, I'd say it was 8/10. Has a very Aronofsky feel. You've got 6 people, each with their equally impressive, yet very diverse talents... all named after different prisons, in which their personalities reflect. We have a teenage prodigy, a mathematician, who must solve huge equations with only her glasses to get herself and the 5 others out of a series of cube-shaped rooms (some are booby-trapped with deadly devices, such as tear gas). We have a doctor, her purpose is to attempt to treat the injured and keep herself and the 5 others alive long enough to get out of the cube device. We have Quentin (obviously named after San Quentin Prison), who is a cop... a very violent, homicidal, opportunistic cop, who mostly just plays the antagonist of the film and keeps it interesting in the mean time. There are others, but the last person that stands out in my mind is Wynn, the savant. He is mentally challenged, but can solve large equations in his mind... when they get further into the cube, he has to help the teenage mathematician, who finds herself starved, sleep-deprived, and without a calculator. Highly recommended.
Shit movie. Not even worth your time. Nothing makes sense in sequence with the first one. No math, no booby traps, no insanity, very anti-climatic. Shit.
Cube 3... meant as a prequel. And suprisingly good! Answers your questions about the first one (most of them, anyway)... some of the plot is without, and not as good as the first one, but very good anyhow. We meet the men who "run" the cube. And one goes inside to try and save a pretty girl who he thinks he may somehow know. 7.5/10
