Many times the question is asked "If you're so critical about the show, why do you keep watching it?" Simple. The emotional depth the show used to have made us care about the characters, as if they were nearly real people. Now, that may sound pathetic to those of you who don't watch the Simpsons for anything more than a laugh... but it's true.
I used to think I watched just for the comedy. The show used to _truly_ be the funniest thing anywhere. But it's strange I haven't stopped watching since the quality of the humor has dropped, and I know why. I think I actually care about these cartoon drawings. Much as you may be emotionally moved at the end of the play "Les Miserables" to cry when Jean Valjean dies (hey... my tough-guy brothers both weeped like babies), or when Bambi's mother is shot, that is the sort of connection I feel for these cartoons. Makes me sound like a super-geek, but I think I'm not alone in this feeling.
Sure, when the show displays its flashes of brilliant humor now and again, I love it. Chris Pfeiler and I disagree about "Bye Bye Nerdie", but at least the episode was reaching back to the pattern of social satire it seemed to have forgotten for a while. There were no groups of characters standing in a circle, simply exchanging dialogue (as in "Tennis the Menace"); there was action, and social commentary. I believe Chris' dislike for the episode stems from the mean treatment of Lisa; but, I saw Lisa displaying no lingering pain--emotional, or physical. She simply decided to figure out the problem, which had a most ironic solution.
At the end, Homer says "So, she just bullies people to get some attention..." Lisa says, "No, Dad! It's the nerd swea--" "Just to get some attention."
That scene is rife with the classic irony the show used to have.
Now, if it were just the humor that came back now and again... I may be satisfied, but I'm not sure. I think more emotional connections and observations should be made throughout the show. The production staff shouldn't shy away from emotionally charged, as well as bitingly satiric material. They used to blend the two masterfully. I think they could do it again, if they tried.
