I watched the original Spanish version undubbed. I couldn't find any extant subtitles, so I had to rely on my fair to middling Spanish. I never read a synopsis before seeing it and wrote my own afterwards to see how much I had gotten, and was surprised it was pretty much spot on, so I think I understood what I was seeing.
Best part: 100% Mexican spaghetti western. Surprisingly few of the Paella sub-genre, the Italian-Spanish co-productions are in Spanish. I like the Italian, but I'd like to see a few that take place in Mexico where they're actually speaking Spanish. And it's filmed in Mexico. That part is really great.
I liked the weapons. I'm a re-enactor and member of the Single Action Shooting Society, so I'm always noticing the weapons, techniques and seeing if it matches the time period. I liked these. Pretty much identical to all my replicas, that gave the gun play an added dimension.
Weakest factor? The freaking' SOUNDTRACK. It is awful- in a trite sort of way- beyond imaging. Cringeworthy. They reuse the same awful melody constantly, not only being tedious, but often totally out of emotional sync with the action.
The plot is really simple. Hey, I understood it. Kind of a nice take on the "everyone's a jackass except me" kind of spaghetti western. The special effects cinematography is really awful, like the sound track, though. Everything from dynamite moving a railroad tie about a quarter of an inch to a .45 revolver blowing up a locomotive head on.
I enjoyed it, in spite of the weaknesses, so I have to give it at least a six, though, technically speaking, it's no six. Like I said, I liked it. Maybe I'm just chuffed at the fact I understood the gist of it. If so I guess I shouldn't complain that the plot was pretty simple.
