Ever since we've gotten Disney Plus we've been doing a Simpsons rewatch. We're up to Season 4 now, and haven't hit a bad episode yet. Some of the jokes aged poorly and are very cringey now, and some of the edge has worn off over the years, but the writing is still very, very sharp after all this time.
What strikes me the most, though, is how brilliant Phil Hartman was. Every scene with Troy McClure or Lionel Hutz is dynamite, every word he utters is funny somehow, even if it's not supposed to be. He truly was a comedic genius.
