I too loved the book and the TV drama.
The movie was good, but to be honest the Drama was better. Because of the length of the series it had alot more time to play the story out and, while some may argue that the dramatization was awful, it also allowed them to include those quirky comedy moments that made the show so memorable. (With the help of the new characters Jinkama and Kazuya. There's only so much the residents could provide.)
