Hey! South Park is one of my favorite shows, otherwise I wouldn't be here. ;) There is no problem with the way Muhammed is portrayed on South Park. Hey, I'm Catholic and I thought Cartman screaming "Fuck Jesus!" was hilarious. I have recently been going back and watching episodes online from beginning to end. I'm almost done with season eight. Here's what I have to say so far...
Season 2: Not as good as Season 1 but there were still some very good episodes, such as the cliffhanger ending and Prehistoric Ice Man from this season as well. I thought Not Without My Anus was okay.
Season 3: I'd say this was the lowpoint of the series, but that's understandable since Trey and Matt were overwhelmed with making the movie. Not a lot of memorable episodes with the exception of Rainforest Shmainforest.
Season 7: While not as good as the previous two years, season 7 also produced some good episodes, particularly the second half. My favorites from this season include South Park is Gay! and Christian Rock Hard.
Season 8: Despite Trey and Matt calling this the "year from hell," Season 8 is by far my favorite. Too many winners for me to count but my favorite has to be The Jeffersons.
