For Leone fans mostly. Others will be bored.

Rating: 7/10 (25 June 2020)

I've seen all of Leone's films including 'Colossus of Rhoades' which is actually a better film than this one. 'Sucker' is bloated, has a meandering plot that limps to a resolution of sorts. There is no central antagonist or specific challenge for these characters per se. It's all rather vague.
Morricone's music has it's moments & while I don't think it's a terrible soundtrack it's numbingly repetitive, overused to the point of irritation at times.
The Flashbacks work to a degree but remain amorphous & offer not much in terms of backstory or character development. I get that Coburn pines for that time & this woman & his friend., betrayal is a part of this but nothing is made very clear or compelling.
Coburn & Steger are respectfully fine on their roles. No other characters are built into any kind of reality, thus interest falters due to lack of any attempt for instilling character background or motivation or connection to the central protagonists in any of these characters.
Leone made some great films., 'For a Few Dollars More' IMO being his best western, lean, mean & full of style, action & outrageous / enjoyable characters. This is the director attempting to stretch a bit with a political message & characters than perhaps evolve more as people. Problem is, Leone was better dealing with archtypes and mythology.
I just ordered this on DVD because I am a Leone fan., as well as a fan of Coburn & Steiger and there are numerous individual moments I really enjoy., the stand-out is Steiger's speech concerning the 'revolution' when he say 'my family is my country' he rejects all political manifestos., to which I heartily agree.
Now, this is not a film I'd recommended to a neophyte coming into Leone or Italian westerns in general because it reflects very little of the best that Italian westerns offered as well as what Leone offered in terms of his unigue style.
You want enjoyable then watch either of the other Sergios: Corbucci or Solima both these directors were more consistently entertaining in terms of pure cinema & they knew how to build characters & have them evolve. Leone's real skills were in his visual prowess & myth making abilities., best enjoyed in his earlier westerns.
