You are spot on with your assessment of that show. It is a satire of the emptiness of our popular culture and the shallowness and narcissism that feeds it.
Plus it is laugh out loud funny. Drudge had a photo of Granny Hillary out with her grandbaby and it did remind me of Edina using her grandchild as a prop to impress the swells.
The one who was always high on coke or booze? Another fantastic character.
I may actually have to find that show and watch it again. It's been so long, it will seem almost like new.
