I was just expecting a pulpy Western. And this book is a pulpy Western. But it's written well, and also has some interesting musings upon the topic of greed.
That quote which is famous for not being in the movie isn't in the book either--but it's pretty crude in the book:
"Badges, to god-damned hell with badges! We have no badges. In fact, we don't need badges. I don't have to show you any stinking badges, you god-damned cabrón and ching' tu madre! Come out there from that shit-hole of yours. I have to speak you."
