I like the popular review titled, "A better film that I think it is". Spot on. It is truly unique, and if you collect and like the "Zapata Spaghetti Westerns", and the political undercurrent, then this is a must see. I'll leave it at that. Austin Fisher has done a great job analyzing it in his book on the subject. Good review of it here. He does better than I can, but, suffice to say, still waters run deep.

One problem may be the release. I didn't like watching it in Italian with English subs, since one imagines the action being in English, and the English dubs are really bad. The most important line, the last one in the movie is completely left out! So, perhaps I liked it because I did my own edit with the English track, the Italian subtitles, English subtitles and the HD Italian vid track, so you can mix and match to your heart's content. Yeah, I don't know I'd give it over a 6 if I had to watch the dubbed English version.
