Though it's a primarily comedic cartoon show, King of the Hill gets intense at times. Over the course of its thirteen-season run, the show tackles heavy issues like infidelity, death, grief, and mental illness. Dark moments like these can derail the laughs but the more somber episodes speak to the strength of the program as a whole. For all of its absurdity, this is a show that really makes viewers think.
The shockingly dark segments allow the writers to delve into some extensive character development. Issues like Bill's chronic depression, Hank's troubled relationship with his father, and the female characters' varying levels of insecurity are all explored in the series. While the comedy is always there, serious concerns are given due respect and this results in more than a few surprising insights. King of the Hill is a program that's unafraid to get deep when necessary and whether that means addressing the fragility of the male ego or discussing how it feels to live with the knowledge of impending death, this comedy is a trailblazer.
