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.
Ronny Chieng absolutely sucked as Kahn. Toby Huss (original voice of Kahn) did an admirable impression of Johnny Hardwick's Dale - just sounded maybe a little congested or something.
