Query: Very slow and very surprising .

Third film directed by Sean Penn ( " The Indian Runner " '91 and " The Crossing Guard " '95 ).1. If you don't like slow developing , deeply phychological films - stay away from it .2. Homicide detective Jerry Black ( Jack Nicholson ) at his retirement party . Only 6 hours left " to serve and protect " . A phone call . Young girl is raped and killed in the woods .- Come on Jerry , you are not a cop anymore !- I still have 6 hours to go .The scene is horrifying and he has to tell the parents . Then he has to give a promise to them and to God that he'll find the killer .3. This film is more about the human mind than the investigation in this case . Obsession can drive you crazy ... but you don't know when you reach that point ... you just don't .
