fan of south park since the 1st season, i could not resist to buy them on DVD.
Despite what people say it's a very clever show. I think you can't watch south park in different level. If I have to summarise, one level is the simplistic gags and vusua.
The other level is what are the point of view of the creator of the serie about a given subject or their view in life.
South Park with Futurama are my two favorite american's cartoon TV. If you look back from season 1, the graphics/animation are still OK and compare to the most recent seasons but you can't help to notice an improvement.
Also I have to say there are some very catchy music which in my point of view are better than some pop music of today.
If you like to see better show than Family guy (personal point of view). Just go for it, you won't regret it.
