Hi,
Sam's film making and in the end violent stuff, was not so much about the western, as it was about his own view of things ... and he had the same issue with producers and film studios. I do think that "Wild Bunch" is the best of them all, though the other films have their own bits and pieces that make it attractive. The only one I prefer not to talk about or watch, is "Straw Dogs", which to me is more about taking it all too far, than anything else ... and by that time, I did not think that Sam was with it anymore.
Pat Garrett and Billy the Kid is an interesting movie ... and I think, a joke ... and not supposed to be taken seriously ... can't tell ... but it was nice, if not weird. At the time, the studio made a lot of bruhaha about the music for the film, and of course having Kristofferson and Dylan in there. Not sure the movie is better with them, or not important without them ... and I never could decide if the film was worth it or not.
