Yahoo! News - 'The Simpsons' Hit 350th Episode Milestone: "'That isn't to say we don't do some bad shows now and didn't then. But I say that by and large, the shows we're doing now are just as good as any I've been involved with.'"
I would have to agree. When you press those who claim the show has gone downhill, they admit they haven't watched the show regularly in about 5-10 years. I was not a big fan of the show at first, especially during the Bart-craze. I think it was somewhere around season 6 or 7 when I started to watch it on a regular basis. It has been a marvel of consistency to me. They cram a great many jokes into those brief 22 minutes, a lot of them in the background. How many shows can do that?
