Neither good nor bad.
This was a decent movie. It had enough tension to keep me hooked, the characters were not as interesting, but still tons better than most of the ingrating ones in Cube Zero and it even had some hilarious moments. "Oh dear, I was never very good at philosophy.
I mean, it was a disappointment, but it wasn't TERRIBLE. I give it a 7.
And like I just implied, certainly not as stupid as Cube Zero.
