The incident referenced here actually happened happened in Romania (but could happen anywhere), yet incidentally there's a film with much more gusto about this subject from there which won the Berlin Golden Bear, "Bad Luck Banging", in which a teacher has to face a PTA because of leaked homemade porn. That film is way over the top and filled with useless symbolism, but it's interesting because it evolves from an intellectual exercise into a full-blown satire.
This Hungarian treatment of administrative bullying in a small town over something as trite as a boring Leo Di Caprio film takes a serious approach but remains horribly dry as a result. The school's staff easily relents to a homophobic attack and uses this to exert authority over a defenseless victim, but there's no real conflict. In the German "Teacher's Lounge", a student rallies his class into bullying a teacher after she caught his mother stealing. That film builds into a major confrontation, this one refrains from making any statement. It's just a few predictable talking points and therefore doesn't do its subject any service or justice.
