Yes, I liked it very much. It has similarities with Das Experiment, but I think it's more close to home.
A teacher [who is very left-wing] tries to demonstrate the effects of totalitarian regimes to his class, by conducting a little experiment. Then things go out of control.
It sort of demonstrates how people react to and are influenced by dictatrorial regimes.
