As a long time Simpsons fan, but i haven't really watched the broadcast episodes of the Simpsons much since 1998 so I thought I would throw out my two cents into this debate about the Simpsons going downhill.
After watching this season 13 I have to say its not in this season 13.
I don't know what these people are talking about with the Simpsons decline in quality.
I still give this season five stars because to me this is like a special gift from GOD as some sort of reward for staying alive long enough to be able to watch these episodes on DVD.
One of the best Simpsons episodes of all time is in this season, you know the one when Homer smokes marijuana, with the classic line " and heres a man whos clearly not dead".
Also one of the funniest Simpsons jokes of all time is in this season, The Gay Dog Alliance.
There is also the alltime classic episode featuring ANGRY DAD
Long live the Simpsons
