I saw this film in Brazil earlier this year where it became the highest grossing movie ever in Brazilian cinema, even beating Avatar. Everyone in Brazil was talking about it, and deservedly so, for it is an exciting ride. It also touched a nerve in Brazil because of its explicit portrayal of police and political corruption at the highest level - sadly exemplified just a few days ago by the assassination of Patricia Acioli in Rio. Wagner Moura is great (as ever) as the 'everyman' figure who tries to fight against this corruption. The movie is extremely violent at times but this is not Hollywood violence - it is a genuine portrayal of the brutality and inhumanity of human beings with all the painful and tragic consequences. Some great satirical moments too, such as those involving the ranting, table-thumping TV anchorman, a figure anyone who has watched TV in Brazil will recognise. It is really good to know that all is well in Brazilian cinema.
