I blind bought this on the strength of the reviews here, and I'm glad I did. Most of what I would say has been said better by others; all I want to add is that it's atmospheric, the landscape looks great, and the music is gorgeous, and used effectively. I also think that it benefits greatly from having been produced in the late 60s-early 70s period of Western film, when film-makers were not afraid to play around with standard genre plots and have faith in their audience; overall I'd say it looks vintage, rather than dated.
There are no subtitles on this DVD (the Optimum release; there may be subtitles on the Momentum version that Andy B has reviewed), which is always annoying to say the least, but the sound is ok and the aforementioned music is not intrusive in scenes involving dialogue. Though that's not much help if you're deaf. Perhaps in view of that I should have knocked a star off, but I'm in a good mood, and it's not often one gets to see Charles Bronson bottle-feeding an uninterested foal.
