It's owned by Disney, man. What do you expect? They're gonna run that shit into the ground until the well is completely dry.
Even before it was bought over, it was clear they had run out of ideas. The show should have ended long ago. Personally, I think they should have ended when the Simpsons Movie came out.

I know, it's been on a steady decline for some years now. I just hope they're either able to end the show, or get the humour and plot like what older Simpsons was like.
