The character's character, especially Mom who has now won three Emmys, are getting overdrawn and tiresome even though they're are still some funny bits and superior episodes. The one with the suitcase left on the staircase landing from last season was a riot.
"Curb Your Enthusiasm" from concept to execution is a bold new director for sit-coms. They are usually rather like Shaggy Dog stories where you aren't laughing and rolling on the floor until Larry gets his final comeuppance in the last few minutes of each show.
The HBO idea of leaving more room between seasons is inspired program direction. I can still see Larry bumbling through more ridiculous, dysfunctional messes, but then I could still take another season of "Sex and the City" and the cosmopolitan escapades of the Fab Four (as opposed to the Fab Five!) Ah well, same difference?
