12 Years Later, ‘The Simpsons’ Biggest Sci-Fi Mistake Still Makes No Sense

As a network television institution that has been on the air for nearly 40 years, The Simpsons has more than earned its reputation as 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 few shows could possibly maintain a perfect track record across that much television. Still, one storyline stands out as a rare instance where The Simpsons doesn’t simply miss the mark — it completely botches what should have been one of the show’s most reliable formats. That episode is Season 25’s “Days of Future Future.”
