The absurd premise should be your first hint that this show is hilarious. The characters and plot develop nicely through the episodes.
From shrieking self-obsessed alcoholic Queen Georgiana develops into an understandably damaged, self-centred but not irredeemably so, woman managing the best she can in difficult circumstances.
Anything that could go wrong in her life does, and she reacts accordingly. Not necessarily sensibly, but accordingly. Not everything is her fault, although some of it really is. The band of misfits around her somehow survive.
I'm disappointed to read that it's been cancelled because the end of episode 6 is just leading into the next round of comedy-of-errors!
Nice structural symmetry, having the first and last episodes with very convincing vomit.
