The newest seasons have its ups and downs and it definetly shows that Homer is still a good man at heart. Working on shaping up an old train ride he and Marge rode on when they concieved Lisa. He wasn't even in trouble with Marge in the first place, he did it for the sake of being romantic for their anniversary. It was a great season finale.
That's when I started tuning out, too. There were a FEW funny moments afterwards, most of them shortly after the movie, but nothing really memorable. I finally gave up during season 22 and never looked back.
Yeah, I like to think of the simpsons movie/game as their premature way of ending the series with a decent bang. The show is just living dead at this point but outside sources like the movie and xbox/ps3/wii game have proved they still can be funny.
Yeah, I love the film and I played the heck out of the game. I even like the ride and the theatrical short from last year. They can't seem to be good anymore unless the occasion is extremely special...
