I actually really enjoy The Simpsons still. Is it not as good as it was? A million times worse, of course. But compared to the entirety of mainstream television, The Simpsons remain, even if only slightly so, light-hearted, enjoyable, and colourful.
If they stopped it 12 years ago, it would be remembered as the best show ever to grace our screens. But even as it declines more and more in originality and humour with each passing season, it is still a damn good show, and I'm glad it's still on TV.
