Small town, big hell. An extraordinary performance by the veteran Frances McDormand is responsible for a major uproar developed in a small town in the American Midwest, where everyone knows each other and in a place where even today racist remnants persist. The argument is very clever and portrays the way in which a wounded mother advertises - gigantic posters through - the apathy and the police infamy demanding justice. The director and scriptwriter McDonagh elaborates a description and, mainly, an evolution in all the secondary personages without falling in the facilismo of good very good and bad bad; the interesting thing is that it addresses a dramatic event almost comedy, with much intrigue, action and using the full 2 hours without being able to reproach unnecessary footage, entertaining and without the slightest hint of boredom. And as if it were not enough with a final nothing Manichaean. In my opinion, a very good movie that has brilliant dialogues, with excellent performances and a remarkable soundtrack, which deserves to be recommended.
