Query: In Cold Blood

A nontypical western, this moves from the classic Hollywood western concept of two idiots standing up against one another in "duel mode" to the more realistic human mode "kill them where they stand by whatever means necessary" and does it quite well.People who want escape from gritty reality will hate this film. For those who want to explore the metamorphosis of depictions of the darkest of human emotions from the 1960's on through the rest of the century, it is a reflection of life and reality at any time in history and an example of an attempt at portraying the realities of human nature by a midcentury filmmaker. Although this may not be as pleasing as films like "Oklahoma" or "Casablanca", it performed the mission I have attributed to it as well as, or better than, movies such as "Full Metal Jacket" or "The Green Berets".
