Unlike many westerns made by the Italians during the spaghetti western craze, "Massacre At Grand Canyon" seems to have been a serious attempt to come across more like an American western rather than having done things in the spaghetti western style. The flavorable music sounds more American, the nice-looking Yugoslavian locations look more American, and the screenplay devotes a lot of time to character development over action. Unfortunately, in the attempt to flesh out the characters, the movie unintentionally ends up being surprisingly boring for a great deal of time. There's far too much talk here - I would have gladly given up a lot of the talk for some more action. As for the action, while there are one or two action sequences that are passable, most of the time it comes across as flat and disappointing. Director Sergio Corbucci made some good movies in his career, but this isn't one of them.
