This is an interesting thread.
I've been as fan of Victoria Wood for many years, though almost exclusively because of her "As Seen on TV" series which must be almost 30 years old now.
I think this series was VW at her absolute funniest and though she's produced some OK stuff since (and some brilliant straight writing and ok straight acting), she's never topped it.
I suspect many of her fans stick with her because this series engendered such great affection. She not only wrote brilliant lines, she gave them to other people and created fantastic characters based largely on her observation of the northern working classes, managing to poke fun without condescending, I thought.
Julie Walters is an absolute joy, but it's important to remember that many of her funniest lines or characters were written for her by VW. JW is a wonderful actress but having tried to read her autobiography, I have to conclude she can't write and isn't particularly funny when she tries to do so.
It's a shame that VW peaked so long ago because those of us who stick with her, I'm sure, find some of the stuff she does now unfunny and cringe-worthy. Dinnerladies wasn't very good, though it included some good lines and wonderful imagery (Julie Walters emerging from the caravan wrapped in a blanket and farting absolute class!).
She remains very aware of what makes funny writing. In particular, she has that knack of knowing why some words are funny and some aren't - Kitty - "A shifty looking youth in plimsolls came and waggled my aerial and wolfed my gypsy creams, but that's the comprehensive system for you" - plimsolls and gypsy creams being inherently funny words).
Sadly I think she's just got older and doesn't have the material she had when she was younger. Let's not forget she's raised two children, gone through divorce and depression and come out the other side. I think there's also that element of shyness still remaining, which is why she seems stand-offish.
Having said all of this (you can tell I have great affection for her!), I do think she ought to stop trying now she's almost 60, or at least, stick to writing bittersweet drama because she still does that well eg Housewife 49. I also think she's got an over--inflated sense of her talent now versus her talent back in the day and that wins her no favour.
"She said she was a radical feminist lesbian. I thought, 'what would the Queen Mother do?' so I said 'We shall have fog by teatime'". No less funny 30 years later!
