Incredible. Does it get any dumber than this? Not a chance. The stupidity in this movie would shame even Ed Wood, De Palma, and Woo. If the first part in the series had mediocre dialog and the second one had bad dialog, then this one has cretinous dialog. Amazing. But this time the story has been lowered to the level of the dialog, too. In spite of the acting and the dialog, I liked the first two films, but "Cube Zero" will surely kill the franchise. The utterly moronic plot so obviously stems from the pen of a frustrated left-winger.
I sometimes wonder if such leftists even themselves realize just how anti-democracy and pro-dictatorship they are. In this movie they obviously target the US a democracy. Why don't they target Korea, Iran, Syria, China, Zimbabwe etc. in anti-military movies? Sure, most of these places are hardly likely to produce a cube like this any time soon, but that's beside the point. It's obvious: writers of garbage like this actually admire these kinds of regimes, whether they are aware of it or not. I would even go as far as to say that ANYONE who adamantly attacks US foreign policies all the time, has anti-democratic beliefs in his core.
Back to the movie: apart from being so far-fetched that it isn't even funny any more, the film has many obvious illogicalities. For example, for some reason the two men who supervise the cube have done it for a while and are oblivious to the pain and sadism that the project entails, yet the first one than the other suddenly turn against the system! Anyone who has any idea at all about human nature will see right through this idiocy. Or how about that cretinous character, the one-eyed evil bureaucrat who talks as if he's in a bad Mel Brooks comedy. In fact, as soon as this creature appears the movie loses ALL seriousness and hence any chance of being exciting: it really does become a comedy.
