This isn't the best show on TV, but it's witty most of the time, and there are only a few TV-MA episodes. Some of them are TV-PG, and use little or no bad language except for using other words like "darn" and "shirt" in place of d--n and s--t. But with that said, violence would be used more instead of language.
I'm kind of confused here, because I only watched 2 episodes of the show, and they were TV-PG. Those episodes didn't have much sex, language, or anything that bad in them except for stealing and a kid who said "My uncle's porn smells like salmon." I guess I'll have to watch more.
I could understand why some people might not like this show. The humor can be sort of surreal and sometimes even dry or wry. But I enjoy it. I like the idea of parodying small towns, since I've lived in a small town for all of my 14 years (I know my profile says 17, that's wrong, I'm actually 14) and I'm sick of it. The humor in the show would go over most kids' heads. Most people watching this are probably over the age of 17.
