The Complete Unknown
"Cube" resides somewhere between sci fi and horror. Happily, the horror elements do not eclipse the basic sci fi story line. A seemingly select set of individuals are entrapped in a kind of every-changing Rubik's cube, left to wonder if there is some meaning behind the group's assemblage, which creates all kinds of paranoia and distrust.
An Ever-Changing Maze
One of the members (Nicole de Boer) believes there is a mathematical consistency in the cube's changing structure, and the others follow along. As we go through various perils, it appears as if the cube was constructed for no other reason that to record the responses of human beings within the ever-changing maze.
An Incidious Machine
The cube's utility and purpose seem to have been abandoned by it's creators -- so the entrapped individuals are totally on their own. For me, the Cube represented the world into which modern man has been ensnared -- a world with unpredictable hazard, nearly impossible to traverse, and abandoned by its creators.
More Than Superficial Sci-Fi Horror?
Whether this relevant "higher meaning" was intended by the script writer or not is complete guesswork. The Cube is laden with lethal cubicles, thus the group cannot follow a direct, mathematical course. Along the way there are casualties -- some as a result of the incomprehensible purpose of the Cube itself while other demises are brought on by suspicions and distrust of the collective.
