Film #7 of Are Se7en Plagues Really Necessary? One Seems Sufficient.

"Okay, let's just say we are in this hypercube or whatever... Does this diagram show us how to get out?"
"Well... No. You see a hypercube isn't supposed to be real. It's just a theoretical construct."

I saw the first Cube forever ago, but I didn't think that Hypercube would be that connected to the story in that film for it to matter much. Let's be honest, though, the way these films begin, I wouldn't have known what the hell was going on if I'd just finished watching it seconds before. This one was as interesting to me as the original was back when I saw it. The CGI looks pretty shitty, but I knew it would so it didn't really bother me that much. What did bug me was how certain characters just didn't matter anymore and disappeared from the action for no real reason. Not bad, but not quite what I wanted it to be.
