Great film, Adverage ending

Rating: 7/10 (24 October 2017)

No Country for Old Men had a descent story line, character development, acting, and cinematography, and still managed to disappoint me greatly with its rubbish anticlimactic ending.
What is the purpose of suspense? I couldn't wait to see how the three main characters would interact when they inevitably came together. But the Coens yank the rug out from under the audience by wiping out the protagonist 75% of the way through the movie. Why waste so much time building Llewelyn Moss'(Brolin's) character and emphasizing his resourcefulness if you're going to kill him off so abruptly with no explanation? There's easily an entire scene missing. Fine, I get it: the Mexicans found him. I don't need a rosy ending, but at least reveal how his demise went down. I'm not even asking for a gory shootout sequence; just explain what led up to it. Yes, there is an underlying commentary on fate and humanity, but this movie is also an action/crime thriller where multiple peripheral characters are strangled or blown away by a sociopath's killer. It seems disingenuous to skim over the main character's death.
