On The Lovely Bones

I read The Lovely Bones several years ago and I don't remember much detail other than the gist that the dead girl, Susie Salmon, is looking down on her family from the "in between" as they try to move on with their lives after her violent murder.  Peter Jackson's film version did little to jog my memory.  I don't know if that's a reflection on me needing a lot more ginseng or on  Jackon's interpretation of the book.  Anyway, I thought the film was entertaining but I wasn't necessarily bowled over.  Jackson's visualization of Susie's heaven was pretty interesting and Stanley Tucci made a good serial killer.  [Can there be such a thing as a good serial killer?]  But the other characters-namely Susie's family and her friends-weren't fully developed.  I suppose that's the risk of bringing some books to screen--some nuances get lost on celluloid.
