Well, it wasn't quite a comedy as I expected, but it wasn't decidedely un-funny either. As I got about 2/3 in, I felt it started to drag and get boring.
She comes across as a social, well-educated person, and it can't have been all that funny for a 19-20 year old girl like her to be dragged to the back of beyond by her new husband. She's done quite a good job of presenting it all in a positive light.
I can't see she's especially negative about her neighbours. As with everyone else, including herself and her husband, she creates comedic characters out of people. As far as I understand, she quite liked the Kettle's. It wasn't as if she could do much in eth way to choose her company, she had to make the best of what was available.
