Things move slowly in this part of the world as well. I read the book late last year but the movie itself was only just released here last week. Could be that you're all reading too much into it. Perhaps, Jones' character really has had enough and as title says - It's No Country For Old Men.
Awesome film - first time I've ever felt they 'rushed' it a bit. Awesome baddie!
SPOILER
The bit where he gets killed felt like they just ran out of money & slapt someting in to finishing it.
We watched this on an internet source, and I was half-convinced that they cut up the ending as a marketing ploy to get us to go rent the film! I have to go back and see it again.

Again, pretty much like this whole thread, SPOILER ALERT.
Harju #26 is correct. Chigurh got the money, he went for the wife because he had promised Moss he would, and he has no intention of going after Bell.
In the book, Bell starts every chapter with a musing. You get a couple of these in the movie, but for the most part they have taken them and condensed them into his speech at the end. The moral is, as Fieldgate #29 says, the good are good, the bad are bad ... except it seems the bad are getting worse, and it is indeed "no country for old men" (i.e. those with moral code) anymore.
Ria #31: The book goes into a bit more detail about this (and the girl he meets as well), but to put all this in the movie probably would have made it overlong. I thought the way they did it in the movie was appropriate -- very matter-of-fact and with a sense of inevitability.
The part of the book I did think they could have included was the scene where Chigurh returns the money to its rightful owner and tells him they're going to become business partners. I thought that really drove home the point that evil will always be there, surviving and thriving.

Damned fine! First time I've been motivated to see a film again so soon after. Even ordered the book. Can't wait.
I've found that people either love this movie, or hate it with a passion.
I finally watched it this weekend. Out of 4 adults, I was the only one who enjoyed it.
"Too violent"
"Too slow"
"Zzzzzzz....." ( she went to bed before it was over)
If I can't take my eyes off the screen or get up and take a leak and get a beer without stopping it first, it's a good movie in my book.
The Coen brothers made an outstanding film based upon the earlier success of Fargo.
This was Fargo in Texas, jacked up a little bit.

it has more in common with Blood Simple than Fargo. but I think it stands on its own and has very little to do with either of those films.
I just read the book and am amazed+ at how well the Coens put on screen exactly what was in the book. Same pace, timing, atmosphere, etc. I saw the movie months and months ago, when I was extremely tired and I sort of lost the plot for a bit, and yet reading the book I could hear each of the actors from the movie saying the lines. I have +never seen a book adapted to the screen so well.
TRRK is right about the motivation for going back to the wife later, and I agree with HCLaw that they could have shown Chigurgh talking to the "rightful" owner of the money.
Fantastic film, and fantastic book.
