That's it. That's the final nail in the coffin for me. I don't even care any more. South Park is dead to me.
You have Asperger's so it offends you? So do I, and while yeah, at first I thought it seemed kind of skreeonk up, I got over it after a week. It's still one of my least favorite episodes, but the only point on the disorder was that the name is unfortunate. The real "skreeonk you" of it is the fact it resolved the previous episode's cliffhanger ("You're Getting Old" - Stan's parents divorced, Randy moved out, his friendship with the other children ended, Kyle and Cartman became friends) by literally pressing the reset button. ("We worked it out, pal, surprise!")
The ending of "You're Getting Old" completely acknowledged the show's tired formulas, right here:
Sharon: You do this all the time! First you're obsessed with baseball fights! Then you need to play Warcraft! Then you gotta be a celebrity chef!
Randy: Why can't you ever just support me?!
Sharon: Support what?! Another stupid dream of yours?!
Randy: Face it Sharon, our son turned ten and you feel old!
Sharon: WHAT does our son turning ten have to do with YOU making the same mistakes again and again?!
Randy: Because I'm unhappy, okay?! I've been unhappy for a long time! [Sharon reflects on this for a moment and her voice goes soft]
Sharon: I'm unhappy too. We both are, obviously. How much longer can we keep doing this? It's like, the same shit just happens over and over and, then in a week it just all resets until- it happens again. Every week it's kind of the same story in a different way but ih, it just keeps getting more and more ridiculous.
Randy: I don't know if I've changed or you have. I just feel like I might not have a whole lot of time left and, I want to enjoy it.
Sharon: I want to enjoy it too, but... I can't fake it anymore. You just seem kind of shitty to me.
Randy: You kind of seem shitty to me too.
Sharon: People get older, Randy. People grow apart.
Like I said before - the show has had some really shitty episodes and in my opinion, based on the way it responded to the preceding episode, "Ass Burgers" was shitty - but it's inconsistent. "You're Getting Old" is one of the best episodes they've done in years - it broke the show's formula completely, to the point most fans were quite sure that the remaining seven episodes would only be continuing build-up towards a finale. But the show isn't churning out ONLY shit - there's still good episodes every now and then, and the old seasons weren't all golden either - there's plenty of duds. Season 2 is especially full of 'em.
The real thing in the show's formula that kills it is an increased reliance on running gags - if you don't find gag X or gay Y funny, the entire episode is lost. Last week's "Faith Hilling" is a perfect example as it satirized ridiculous internet memes. If you didn't find the "Ohh Long Johnson" cat meme or the titular "Faith Hilling" meme funny, pretty much the entire episode is lost after the first eight minutes when the cat plot is introduced. If you do the running gag of the week hilarious, then it'll be a great episode, but if it fails, it can't support itself unless there's a really big emotional hinge. "You're Getting Old" has some really unfunny humor at times, but it contributed to the story and episode's emotion, because if you found it disgusting, you could sympathize with Stan's own discomfort more - it worked on both an emotional and comedic level.
And really, the quality has dropped, but it's doing a lot better than "Family Guy", which seems unable to hinge itself on humor anymore, which is probably why it's been so stuck on the more serious and dramatic plotlines in an attempt to make up for it (Which I enjoy to a degree, but it IS a comedy show.)
