Yeah, they're on DVD. There's 3 total. Cube, Cube 2: Hypercube & Cube 0.

Loved Cube, liked Cube 2, liked Cube 0 a lot.

Cube was great, but I havent bothered with the sequels yet.

I thought the first one was great, never saw the second one and liked the third. The third one I took it as a prequel to the first one.

the first one was awesome, was very dissapointed with cube 2 definately the worst of the 3, Cube Zero was pretty good

I loved Cube, was very dissapointed with Cube 2 and haven't seen Cube 3. I liked the dicer seen from the 1st I would have to watch them again to know for sure as I don't remember any others specifically.

I looved Cube. It was so good I suggested it to my math teacher. I got bad grades after that, but the point is it was a really original movie. The sequels were pretty lame though.

I actually watched Cube Zero first, then cheeba recommended to me to see Cube.
I got all 3 of em on DVD, and I was thoroughly entertained by the original and Zero.
Hypercube was decent IMO, but not as good as the 1st and 3rd.
