The time skip feels natural, and even though I was initially skeptical about the premise that Hank and Peggy moved to Saudi Arabia for years (seems so out of character for them), I now appreciate how it allows us to see the Hills react to the ways life in the US has changed. It was a great choice.
I never really watched the original series, since it's a boring offshoot of Beavis and Butthead, but I love little moments of it. Great characters, kind of boring stories.
It feels like a less wholesome, animated version of Joe Pera.
