After seeing the original Cube, this movie is pretty bad. The people in the first movie actually all had to work together to get out of the Cube. And each one had a specific talent that made up the puzzle in getting out of it (i.e. no one person could get out alone). In this new movie the concept is the same but is never developed! People are just mindlessly roaming from room to room with no plan. The older woman supposedly has superior mathematical ability that should be able to decipher what the number 60659 means in each room, but she is too senile to do so! She's also quite annoying and adds nothing to the movie.
The blind girl was suppose to blow the whistle on the whole thing, but is found out before doing so, so she escapes into the Hypercube. Never mind the fact that even though she can barely move from room to room due to her blindness, she has miraculously waltzed into the Hypercube!
Traps have no logic to them, other then the eye candy factor.
The ending: very weak and it doesn't make sense.
Overall, a very disappointing movie to the first.
