Did not age well, low budget, low production values, low quality overall

Rating: 4/10 (2 January 2017)

The biggest problem of this film is not its small budget, but the fact that it's not a very good idea to begin with and it's hurdled by its small budget.
I've seen better films done with a guy and a girl in a coffee shop. A good film starts with the script. This script is something I would not read. It's just not good. A prison of random people who have to navigate from room to room inside a cube doing math. What? Why?
What would a bigger budget mean? More cube rooms? More colors? Higher profile actors?
You could get Tom Cruise, Clooney, Theron and co. and this still wouldn't be a better film.
Nothing is explained at the end. I don't know why anyone would design a cube like that or have a prison with the possibility of an escape if you work together. Even in ancient times there were prisons were you can't escape. So why would the military-industrial complex build such a weak prison?
It is implied that the state is responsible for this, not some psycho like Saw.
But what's the point?
