When the mind thinks of the densest, most sprawling narratives realized over the past couple of decades, the kaiju-influenced action show Power Rangers usually doesn’t pop up first. But a quick scan online would reveal that the series has run for a mind-boggling 837 episodes (and counting!) over the course of 24 seasons since 1993. The series has assumed many forms since then, rebooting itself as a show about ninjas (Power Rangers Ninja Storm), samurai (Power Rangers Super Samurai) and dinosaur-themed warriors (Power Rangers Dino Thunder, Power Rangers Dino Charge, and Power Rangers Dino Super Charge — kids love their dinios). It is, by anybody’s measure, a lot of television.
