i can respect that, because i know that there are 2 kinds of South park fans: Fans that thought it used to be better in the old days, and fans that think its way better these days.
The reason i think the current ones blow the old ones away (big time) is because it's less fart/bathroom/swear jokes, and more outrageous politically-influenced humor, where Trey is taking it as far as he can go on network television.
Its just getting so extreme that every episode becomes more unbelievable than the last.. like "are they really aloud to do this on TV?". A few of the new-season episodes have been average, but some have been funny as fuck, and thats more than most cartoons can say at this point, including Fam Guy and the Simpsons
