Latter-Day Simpsons... Anything Good?

Well, five days and a hundred-some-odd episodes later, the Simpsons marathon has hit Terra, or possibly Guy Incognito. Yes, I still watched the show after Season 9, but by that point it's safe to say I'd lost my religion. In fact, I'd pretty much stopped following the series by the early 2000s, tuning in only occasionally during brief moments of curiosity, boredom, or drunkenness.

Was I misguided in my approach? Were there good episodes after Frank Grimes and Armin Tamzarian, and Lionel Hutz and Troy McClure joined Snowball I and Bleeding Gums Murphy in the afterlife? (Yes, I saw the LEGO one.) Anything worth checking out?
