I love the Cubes!
Cube 2 is weird. They're in the "Hypercube," but it's just the same shit, except with a twist ending. The Hypercube is all clean and glowing, which really hurts the movie. They've lost that grungy stuff. The traps are stupid, too. Bad special efects. But, hey, it doesn't really suck. I wasn't offended by it.
Cube 0 is my favorite.
