Part of the problem with Kath & Kim is that the characters they created in the U.S. version are just one-joke wonders.

And maybe this is the problem... the principle's fine, but the execution is sometime's lacking. I also think from the UK context we are so familiar with US films and TV that we don't actually need it recontextualising... personally I am okay with this and always groan inwardly when some of my country folks moan about too many American shows on TV... especially as my experience of watching TV in the States suggests by-and-large we tend to get the good ones...

Not hot air, Ron. Merely warm. And pleasingly moist...
