Has "Vicious" improved? Series 1 Christmas episode, ITV

Against my better judgement I gave this tepid sitcom another go, bearing in mind how great Derek Jacobi was in Series 2 of "Last Tango in Halifax".
Nothing has changed. Obviously filmed straight after Episode 6, early in 2013. Same tired dialogue and obvious, crass situations ("Truth or Dare" resulted in Frances de la Tour having to mention Ash's penis). She must go home, look at the script and cry.
The studio audience must have been primed up with booze and chocs - laughing at almost anything (e.g. Ash's comments about his perennially drunk mother brought inappropriate titters).
How this waddle deserves a second season is beyond me. Perhaps if there was more mincing in "The Hour" and "Ripper Street" BBC wouldn't have cancelled both. No, silly comment, these were big budget dramas, whereas this sitcom is cheap (and nasty).
I know it's called "Vicious" but Gary Janetti ("Will and Grace", "Family Guy") seems to have forgotten how to write funny, gay stuff.
America's PBS has bought the rights (the prestigious cast must been a factor). Didn't they watch it?

Observation:
This dross reminds me of Stanley ("Singing in the Rain") Donen's 1969 misfire "Staircase" starring Richard Burton and Rex Harrison as the aging queens. Perhaps the play was better.
