CUBE was definitely a great film, right in line with Ghouk's recommendations. Both sequels were just so-so, in my opinion. CUBE ZERO is much more like a B-movie than the original CUBE, though, which makes it sort of fun. But it's too literal, explaining too much and taking away the mystery of the Cube, which was the best part of the series.
I agree. I liked Cube Zero, but it kind of spoiled the original by giving too many answers. The ambiguity was the whole point.
Cube 2 was definitely the weakest of the three, but it had some clever ideas, and I really loved (spoiler) when Geraint Wyn Davies goes nuts amid all of the converging parallel realities and time moving at different speeds, and manages to survive for years by killing and cannibalizing alternate versions of the same guy over and over again.
But the original Cube is still the best, and probably should have been left to stand on its own.
