M (ein Stadt sucht ein Moerder): Fritz Lang's first (partial) sound film. Draws disturbing parallels between police and criminal organisations, while also managing to condemn vigilantism.
If...: A good counterargument to anybody who claims that all these teenage rioters need is strong authority figures and military discipline.
Beguiled: Proof that it's not just male schoolchildren who can go, homicidally, off the rails.
Baader-Meinhof Complex: Scary docudrama about the German terrorist organisation, providing context for their actions while also revealing the brutal infighting within the group. Also draws disturbing parallels between police and criminal organisations, while managing to condemn vigilantism. Costarring the ubiquitous Bruno "Hitler" Ganz.
