Ok, this is the first time I've had to order a South Park boxset online. Normally, on their release date they are available in Tesco or Asda. However, this was not. I ordered it and received it very quickly. This series I have to say, is not South Park at it's best. It doe's have some genius moments that had me laughing away to myself but it was not consistent enough. Reverse Cowgirl, Butterballs and Raising the Bar where the standouts. However, while the show prides itself on it's "6 days to air" approach, it's starting to become very obvious that the episodes are being "thrown" together. There are too many moments where you are left wondering "what was the all about". Also the ziplining episode, in my opinion, is the worst episode they ever done. The only other criticism I have is that as each season goes by, Cartman seems to be getting kind of annoying. He always was an obnoxious little boy but now he's really starting to piss me off and I'm finding it hard to respect his authoritah!
Don't get me wrong, if you are a fan you will enjoy it, and some of the things it adresses are still fresh and up to date...but if you are new to the show, try earlier seasons.
