But aren't all the characters busybodies to some extent or other?
Yes, except perhaps for Cain, and I dislike quite a lot of them too, not just for being busybodies. Top of my list would be Will and Amy. Probably be easier for me to list those I actually like.
true but wendy really irks me and i liked the actress in casualty
I agree, there is just something about Wendy I find unlikable. Betty Egleton and Edna Birch, were first class, professioal premier league busybodies, but I found them enjoyable and entertaining, even though I might not have liked their characters in real life.
