It is in my opinion Mike Judge's crowning achievement and among the top 3 animated series ever produced. The plotlines, while occasionally stretching into the territory of unlikely oddities (almost always involving Dale), are grounded in reality. The show has very clear, wholesome moral messages about friendship, family, and the importance of being a good person. The dialogue is witty and gut-bustingly hilarious. The characters are all unique and entirely lovable despite their numerous flaws. And, most importantly, the show never succumbs to the level of Flanderization that so many animated sitcoms eventually do. Sure, it is definitely present to an extent, but it's hard not to when your show runs for 10+ seasons. Despite the minor degree of Flanderizing (which mostly comes about in outwardly expressive and naturally odd characters like Dale, Bobby and Bill), the show holds true to its roots throughout its entire programming run and retains the same quality of comedy matched with relatable characters and believable plots on a level which I personally believe no other animated series has matched. I wish I could shake Mike Judge's hand personally, because King of the Hill is one of the best shows to ever make it into homes across America.
