Surely not your typical Western...there were several times where it felt time to wrap it up...I didn't understand why the movie was still going, why were you still telling this story?
The film has action and lots of loud gunplay, but Audiard's direction tends to tease out the story's quieter moments, favoring characterization and dialogue.
For every revelation woven into the action, there's a bit of obvious philosophizing to remind you of the real point here. (It sure ain't the gunplay, though the way the six-guns spit sparks is fun to look at.)
The Sisters Brothers might have some of the conventions of a typical western, but it surpasses them with a surprising touch of warmth and humanity. [Full Review in Spanish]
It aerates what's already been well-trod, offering an alternately pitiless and tenderhearted lens on such hardy themes as character, filial loyalty and American progress at its most naive and voraciously destructive.
The movie works, it well and truly works, because the four main characters come together in ways we could never have foreseen, and the actors themselves seem surprised at the twists the story takes and where their characters fall on the curve.
