There has been a lot of hate for this TV show. Many say the jokes are predictable, offensive and disgusting. Sure, the comedy is dark. In fact, it can get very dark at times. However, it is still a funny show. The comedy is so out there that you are genuinely surprised with some of the things that the characters say, even if it was just a side comment. Although these jokes could be considered predictable, it is their unpredictable placement that makes it great to watch. Some of the humour was a bit cringey, which made me glad that I watched many of these episodes on my own. But these weren't too common (either that, or I am not easily embarrassed!).
When the series starts you aren't told much about the characters aside from their generic traits. You learn the odd thing about each character (for example, a certain someone's love for more mature women), but don't expect it to expand much beyond that. It was quite interesting for them to do this as most cartoons give their characters some back story. It means that each episode is a surprise when they are thrown into highly unlikely situations in an unassuming National Park.
I would recommend this show to people of my age (college/university). It is definitely a show for the more mature individual. I am sad they no longer make new episodes, but I have enjoyed what they brought out nonetheless!
