I trawled through a list compiled by Monster Children called the Ten Best Movies of 2015 You Maybe Missed in search of treat that in fact I had missed. I found that treat, and it was the best movie I watched in 2015.
The Stanford Prison Experiment is the dramatised story of a real experiment that was conducted in the 1970's involving young men from the Stanford area in a simulated prison. Half were guards, half were prisoners.
Stanford's motto is 'The Wind of Freedom Blows'. This experiment was pretty far from that.
