"Go West" is not as well-regarded as some other Buster Keaton films such as "The General" and "Our Hospitality," but it's certainly worth seeing. And at only 69 minutes, it doesn't require much of a commitment.
Down-on-his-luck "Friendless" heads west (Keaton sure did love train scenes) and grabs some work as a cowboy, despite being a complete novice. He can't ride, can't shoot and can't milk a cow. When he pulls a stone out of a limping cow's hoof and the grateful beast becomes devoted to him a la "Androcles and the Lion," it seems like a sweet gag. Surprising that this idea becomes the central plot -- it's not much to hang a movie on. However, the climatic cattle drive through the streets of Los Angeles is a set piece that can't be missed.
