The movie (or more accurately series) is very good too. I loved the book when it came out, and read it often enough that I can quote lines from it. Usually, knowing a book well makes one less inclined to like the movie, but I enjoyed that a lot.
Time for funny anecdote. We live in relatively remote mountains, near Silicon Valley. There is a deep valley near our house, which is difficult to inhabit (no electricity, nasty terrain, water sources are small springs and seasonal creeks, no paved road, some areas only accessible via seasonal temporary bridges), and the folks who live there are refugees from society: outcasts, drug addicts, psychological problems, released criminals. One family there are ultra-conservative christians, who want to live far away from the sins of modern society (20 minutes from Silicon Valley!), and raise their children in near perfect isolation. To do that, they have chickens and a large vegetable garden. Another person there is a vietnam veteran and multiple-times convicted criminal (drugs, guns), who keeps a few small pigs as pets: they are his best friends, and after a while he eats them. Well, one day one of his pigs got away, and ran to the christian's vegetable garden. He ran after it to catch it, and while trying to catch and recover it, he said some words they didn't like, like f*** and s***. They didn't like those words so badly that they beat him up. So badly that he called the sheriff, and they were arrested. It leads to a court case, where they defend themselves by saying: their kids having to hear these 4-letter words is so offensive, it gives them the right to stop those words from being said. Well, the judge didn't agree, and restraining orders were issued by the judge. Which didn't make things better, it just transferred the vendetta to different victims: the chickens died. Then one of the pigs died of a gun shot wound, and we can safely assume that it was not self-inflicted (pigs don't have trigger fingers). Unfortunately, the area doesn't have electricity (no refrigerated storage), so a small part of the pig had to be prepared and roasted right away, and the rest was wasted.
This was several years ago; the parties involved still live there (well, except for the chickens and pigs which remain dead), and I have no heard of further murder and mayhem from them. Now, imagine being a regular police officer (we call them sheriff's deputies here), and being called to deal with 4-letter words, beatings, and dead pets. That's why being a cop is such a hard job.
