For a long time, the Stormtroopers were Star Wars' running joke. The Empire's hired goons have a tendency to do what hired goons always do: get thumped by the heroes en masse. After a brief bout of competency in the opening of Star Wars: Episode IV - A New Hope, they slip into expected form to the point where they -- and the Empire itself -- are undone by a tribe of teddy bears with pointy sticks. More recent Star Wars projects such as Star Wars: The Bad Batch and Andor provide a beautiful bit of retconning by demonstrating exactly how the Empire's elite soldiers fell into disrepair. The move allows the joke to remain while integrating it seamlessly into the Star Wars universe.
