Yeah but seasons 7-8 are solid and fun to watch. 

Old man and the lisa, Homer's enemy, mountain of madness, twisted world of Marge simpson, and mysterious voyage of our Homer are all season 8.

Season 8 was peak simpsons IMO.

I personally think it's still enjoyable around season 10 or 11 but after that it's just a steady downhill streak.
