I think Victoria Wood USED to be very funny indeed, but that sketch show (which I was so looking forward to seeing) at Christmas was awful.
Dinnerladies was excellent, the dialogue was brilliant I think, and the strange conversational tangents all teh characters went down. And brilliant acting by everyone in it.
And also Acorn Antiques was excellent. Ooh I do adore Celia Imrie.
Julie Walters was far funnier in the past when she was just a character actress and not a bloody national treasure playing characters with terminal illnesses.
Some old comedy shows do bear up to repeated viewing - Fawlty Towers, Blackadder, Rising Damp, Porridge will never date. However some old shows I think are dire - I saw an episode of Bread recently and it was awful, so not funny, and Some Mothers Do have Em makes me cringe. And WHAT the hell was Keeping Up Appearances all about looking back now. Awful.
French and Saunders was never bloody funny, look at the travesty of the Vicar of Dibley for crying out loud.
