My biggest problem with the movie
I can forgive plotholes, lame characters, etc. etc. as long as the "action" or intensity gets to me. This movie had none.
When everything is possible, you expect everything, and then nothing suprises/shocks you.
P.S. why were they so insistent on "moving forward"? after they realized every cube could be an entirely different dimension, what exactly would "moving forward" actually do?
