'The Simpsons' Is One of the Greatest Sitcoms of All Time, but It Completely Botched This Sci-Fi Storyline

As a network television program, it’s safe to say that you don’t last for nearly 40 years on air if you’re mediocre at best, which in turn would mean that The Simpsons is one of television’s greatest all-time sitcoms. There have been episodes that aren’t especially good (I still contend “Moe’s Bar Rag” is the worst), even entire seasons, but for the most part the track record is uncontested. But one storyline in particular not only isn’t great, it’s completely and utterly botched, a misfire on a series that doesn't typically botch their storylines, good or not. That episode is Season 25's “Days of Future Future.”
