The movie is entitled "A Long Line of Crosses" and I suggest watching it in Italian with subtitles to appreciate what it was supposed to be like. American release titles are often 100% marketing in the genre, and have NOTHING to do with the movie or the people that made it. This has to be the most extreme example. I don't think it counts as a spoiler to note that a) There is no Django in this, and b) there is no hanging. There's no long line of crosses for that matter, but it's an apt title.
For me, there are four major classes in the genre. First, those that are great movies outside the genre, second, those that are not as good as that but better than the average example, those that are fair to middling and those that are below par. For me, this was a solid example of the second class.
It's slightly over the top in terms of self-consciousness of the genre, but that's OK for lovers of Spaghetti Westerns. Yeah, we can see The Preacher is obviously an imitation of Klaus Kinski in The Great Silence and lots of other over the top flourishes, but they never detract from the flow. I enjoyed it.
Many of the genre were social commentaries on American's place and actions in the world and issues of concern to progressives in the 1960s. This one does that solidly, but gets so much right about US/Mexico border issues that it is still relevant as I write this in 2016. I would have given this 7/10, but that raises it a point in my estimation.
Meal pairing suggestion: Camarones a la Diabola with rice and refried beans and flour tortillas.
