Boy this movie's a real stinker. It tried in some respects to be just like the original, what with the people plucked seemingly at random from their lives and put into this facility of cubical rooms, each with six doors out and into the neighboring rooms. But other than that it's like a cheap knockoff. Halfway through and there's only been one death, and we didn't even get to see it! None of the rooms have any traps, and while the first person we saw was missing a shoe, that seemed to just be an easter egg nod to the original.

The addition of quantum theory was an interesting choice, but wasn't executed well and just ended up being super confusing. Extend a cube into a fourth dimension, but the fourth dimension _isn't time?_ What does that even mean? Okay, there are parallel universes, meaning we have multiples of the same characters running around in this place, but to what end, why would someone want that?

Also none of the characters are likeable at all. I was waiting for most of them to die just so I wouldn't have to listen to them anymore. One of the great things about the original was how everyone had something to contribute to the group in their efforts to navigate and get out, and the jerk character ended up being a good person, while the seemingly good guy ended up being a really really bad person. In this, too many people had secret identities or ended up being completely inconsequential. Also why did Max and Julia decide to bang? No one knows.

The ending was rushed and didn't make much sense, but I'll admit I was more engaged in the last ten minutes than I was for the entire rest of the movie. I guess it's worth a watch if you liked the first one, but it's not connected to the plot of the first one in any way, and doesn't explain anything from it; if anything, it just creates more questions.
