now's the time to read the book!

No way - such thinly veiled Christian propagandising has no place on a Dr Who thread. Kids get Traditional Stories on a level no adult ever could - adults areway too sophisticated to get the immediacy of it, Dr Who likewise. I think Robert Cormier had it about right - when they made the film of The Chocolate War he was forced to rewrite the ending to make it apealing to adults - or at least what adults thought was more suitable to a kids film - but kids faithful to to the novel were justifiably outraged by the untypical up-ending (in every sense). The most disturbing book I ever read (Cormier's stuff notwithstanding) was Diana Wynne-Jones Fire and Hemlock which pitches True Thomas and Tam Lin into a twisted tale of evident evil and imminent adulthood; a kids book, but as an adult I doubt I got the half!
