The book is a pretty fun ride. As many before wrote it indeed is a totally slapstick, which I actually love a lot. Anyway, I hoped a bit for "A Perfect Romance" perfect clone, which (sadly for me) didn't happen as these two books are nothing alike.
I feel maybe the things haven't worked out exactly as the author wanted. There is a quite gloomy undertone in the book to the more visible farce quality, which actually gets even more serious and a rather grim later on. Nevertheless, mix these things together and it can make for a touch ridiculous package sometimes.
