I think that my view of the book was influenced by listening to the audiobook. Colin Firth does an amazing job of capturing the emotional tone of the characters such that I did not get the feeling of an overwrought YA novel. I felt it was very human capturing a range of emotions that people might really experience. We are imperfect, fallible creatures.
Of course, as they say, I could probably listen to Colin Firth read the phone book and enjoy it!
