A fascinating watch in light of the fact we now know where this show was headed - to the absolute top of the pile. South Park isn't just one of the best animated shows of all time - it is quite simply one of the most important and consistently brilliant shows period. As an animated Vice President would most likely attest in a future episode - I'm being super cereal.
This first series is incredibly dated now and it can be almost uncomfortable to watch at times. Nothing feels quite right - the dialogue doesn't flow like it should, the animation (particularly of character's mouths) is so much simpler, the storylines less sophisticated and the humour more basic (perhaps more innocent).
You can see how many good choices were made as the show developed - the Cartman character is now even more prominent, the dialogue is so much snappier (esp between Kyle, Stan and Cartman), the running gags (Kenny dying, Chef singing, Stan puking, etc) were chopped, rubbish characters were jettisoned (Pip, the class bullies) and better ones added (Butters, Jimmy). The improvements in the animation and reduction in the length of time it takes to record episodes allowed the show to become increasingly topical which I personally prefer.
This is not to say there aren't some great moments contained in these embryonic episodes - the genetic engineer with a weird fetish, Stan's horrific sister, Cartman's unhealthy yet endearing relationship with his mother, Mr Garrison's totally inappropriate political diatribes, etc.
Worth another watch for hardcore South Park fans although I believe the show really started to get off the ground around series 3 and 4 and is still in rude health to this very day.
