I just bought season 4 on DVD and every episode is brilliant. About the last 4 or 5 years of the Simpsons hasn't produced but a few episodes that even comes close to comparing to any of these. What's going on here? Are they really out of ideas anymore, and/or are the writers now really that bad? I guess it's understandable, after 14 years it's gotta be hard to produce quality episodes. I think the Simpsons should have done what Sienfeld did and opt out on top after season 9. It's really been downhill since.
