Simple, yet never the same, The Simpsons holds the creative bar for opening credit cartoon sequences. From Bart’s chalkboard lines of the day to the famous couch gag, the genius behind the intro is in its variety. As entertaining as the show is itself, the opening has lived through hundreds of iterations in The Simpsons‘s two-decade history, each with their own subtle or startling tweaks. This version, which features a snippet of the famous score from Stanley Kubrick’s 2001: A Space Odyssey, shoots us up into the cosmos for an alien’s eye view of Springfield. After 22 seasons, it’s this inventiveness that keeps us tuning in.
