Careless but fun!

Rating: 8/10 (5 October 2005)

Sure, the characterization is a little heavy-handed, but isn't the math concept pure excitement? If only they were a bit more careful with their numbers... And as for many, many reviewers who went huh when the prime numbers were presented... hello, people. I don't know what about the US, but in most European countries, this stuff is taught in basic schools. By the way, 4 cannot be a prime number. But, in the movie, it is. Obviously, the screenwriters didn't go to school either.
But aside from that, it is a fun indie movie that squeezes everything out of its potential. The eerie and futuristic cube is pretty, the traps are maybe not the most original in existence (although the first scene was good enough to get ripped off in another, much more expensive and wide-released film), and the low budget doesn't keep it from being highly entertaining.
