I'll call it friend-o. You're last act ruins the whole movie.
Great characters, dialogue, locations, all inside of a simple, straightforward and compelling plot.
However, the story unexpectedly switches from a thriller to a character study in the last act. The relief from the suspense, the satisfaction of victory or the tragedy of failure are deprived from us, and naturally, it is disappointing.
Apparently, the Coen brothers were being true to the book. I say that was a mistake.
There were certain elements that seemed like they didn't know what they were doing.
The protagonist gets killed off screen and not by the antagonist. The viewer either wants the satisfaction of his success or the tragedy of his demise. We were given neither.
The Woody Harrelson character finds the sought after money effortlessly and implausibly. Not that he couldn't have found the money, but it could have been done believably. As far as the viewer is concerned, Woody was walking down the sidewalk and happened to step up onto the barrier for a view into the brush below for no reason, only to see the lost money.
Tommy Lee Jones goes to the hotel where the hero was murdered. We see the villain hiding in the shadows. We expect a confrontation. Then, somehow, someway, the villain is not in the room. How? What happened?
The damsel in distress doesn't run when the villain comes for her. Why? I hear it was because she just lost her mother and husband and given up. It wasn't presented that way. It seemed like the plot needed her to have a conversation with the villain, so she did.
As one viewer muttered at the end, "didn't show me anything I didn't already know."
Interesting point. Too-often, life appears as meaningless random acts, often violent, that we have no control over. There is nothing wrong with a movie that portrays that, but the filmmakers needs to manage expectations or suffer those comments. We were setup for a big payoff, and got none. A filmmaker can only expect disappointment when they do that.
I have no idea what the conversation Tommy Lee Jones had with the old man in the wheel chair meant. Much less, who the guy in the wheel chair was or even follow what they were saying.
The movie is receiving across the board great reviews. Pretty much everything about the film is great except for what I mention above. And the problems above are so fundamental, so foundational, it makes everything else half as good as it could be.
