The problem with The Goode Family is the same problem I have rewatching the first season of American Dad. King of the Hill may have meant to be a parody of southern conservatives, but it really becomes more of a series about how Hank Hill is a button down guy who just doesn't get modern ideologies, and as he has a quirky set of neighbors and family members, he's the one that's relatable and sane and it went from Hank being incredibly, comedically button down to the reasonable, rational one that tries to maintain a level of sanity within his family and friends. To the point where it got really formulaic in the last season, and I think it ended before it became too repetitive.
Where as the Goode family is a stronger parody, one that's not quite as affectionate of suburban leftists to the point where
they are the odd ones in the neighborhood. It's not exactly cartoonish, but far less subtle than KOTH was. But the thing that would have fixed it was time and more episodes. Early on, Hank was on the hilariously uptight side, but he evolved into a more human character very early on. There were signs of small character evolution for Gerald, and they did have that episode where they were banned from Whole Foods and had to shop at a Cost-Co expy. And if there's one thing I think they did hilariously well was that the lower class buy in bulk types... ehhh...a phenomenon I've noticed is how the cheaper the grocery store you go to, the less attractive people get, so that's a nice gag that's never been done.
The Goode Family isn't a bad show, just one that never got to reach its potential. I'd say another season or even a handful more of first season episodes, and it would have been good. Not KOTH level, obviously, but still a decent show.
Also, the voice Mike Judge used for Gerald Goode is just the hippie teacher from Beavis & Butt-Head, not Hank Hill with a stuffy nose.
And Hank Hill's voice is that of Mr. Anderson, also from B&B, to the point where they almost considered making Tom Anderson Hank's father... but then we wouldn't have had Hank's
actual father, so that worked out for the best. And this also gets hilariously lampshaded in the book "That Boy Ain't Right," where under Hank's movie picks and pans, he mentions catching "Beavis and Butt-Head do America" on TV at a motel and saying something about how that Tom Anderson guy has a very annoying voice.
