Thoroughly enjoyed. Since nothing much really happens , the strength is absolutely in the characterizations and Rowling does a stellar job of getting inside people's heads and portraying the subtle nuances of personality. I found myself so many times loathing a character only to find I was sympathising with them a few pages later. 
 I live in a very small town where everyone knows everyone's business and I thought the sense of suffocating smallness of Pagford was so well written. I could really relate to the internal politics and the feeling of not being able to escape from them no matter where or what you were doing. "Whose side are you on" and of not being able to walk down the street without seeing someone you know and who might see you talking to that person...very very real. 
 The different relationships between the teenagers and their hapless parents were downright scary though and really bought a sense of grittiness to the book. 
 Excellent.
