I’m going to agree with Tom Tildrum and not with Stringbean. It’s still recognizably the same show.
I still try to catch every new epsode that comes on (I did so last night), and I usually enjoy them. Not as much as during the show’s “golden age,” but that’s partly because the quality isn’t as consistently high, either from week to week or within an episode, and partly because so many things have already been done and it’s lost its freshness and novelty. Balancing the latter, though, for me at least, is the familiarity and comfort of knowing that The Simpsons is still around, still putting out new episodes as they have been for pretty much my entire adult life, and as long as that remains so, the World I Knew will not have entirely disappeared.
