An intelligent horror film that is equal parts mathematical acumen and very realistic gore, CUBE ZERO is the third installment in the popular Canadian indie CUBE series. A prequel to the first, the central scheme is the same: a diverse group of individuals prone to infighting wake up in a booby trap-laden cube where one identical chamber leads to another. With no exit in sight, they are forced to get along and make use of their respective talents, but many--usually those with the most antagonistic personalities--are lost along the way. This installment, however, provides some answers the mystery of the Cube, with a subplot involving a technician on the "other side" who experiences a change of heart, and undertakes to save the group in a most unexpected way. An improvement on the last installment in the series, CUBE ZERO provides characters the audience can care about as well as some ingenious ways of killing off its bad guys.
