some of the colourful brazilian slang is lost in translation, but it's still a fine movie. for example, the character knockout ned is mané galinha (galinha = chicken), because in brazil that means a guy who gets lots of girls; a nobody/poor person is called "pé de chinelo", or "sandal-foot". people who deliver drugs are called aviãozinho (little airplane) or vapor. stuff like that.there's also Tropa de Elite/Elite Squad (plus the sequel, which i haven't seen yet), similar favela/drug tale but told from the police point of view. there's an attempt to show how different things can be a part of the problem (poverty, gangs, corruption, the middle class, police) but it handles it a bit clumsily. it also sort of condones the BOPE elite police's extremely violent practises, but if you can let that slide it's pretty entertaining.
