This movie underlines that man is a social creature. We naturally form groups, groups of friends, of people who like the same music etc. Especially when we are young, belonging to a group is important, it makes our identity, who we are -- as opposed to who everyone else is. And so the teacher in the movie uses what is naturally there, to teach his pupils about autocracy. It shows what happens when you stress that identity, when you stress the sameness, and thus also the otherness of those not belonging to the group. Eventually it shows how easy it is for one, for the group to slip, even without being aware of it. Autocracy isn't dead, it is alive and it is easy. This movie is a must see for everyone, but especially for the young.
