Many explanations have been offered for the creative decline of The Simpsons, from standard seasonal rot to the alleged tyranny of former showrunner Mike Scully. But one of the most persistent theories has been that when Matt Groening created Futurama with Simpsons writer David X. Cohen, he took the best of The Simpsons’ staff with him. While the work of Cohen and other former Simpsons scribes who migrated to Futurama like Ken Keeler, Bill Oakley, and Josh Weinstein cannot be overlooked, the truth of the series’s fall from grace is far more complicated.
But it’s not hard to see why the Futurama theory is so appealing. Futurama came about right when The Simpsons started to lose its fastball. And though Futurama has had its fourth, and presumably final, series finale, while The Simpsons marches on, in many ways Futurama feels like the spiritual successor to The Simpsons’ greatest years. No other show has been better able to replicate the peculiar alchemy of Springfield—the combination of a cynical worldview, a devotion to absurdist humor, and an undeniable grounding in real heart and character moments—than Futurama.
