Have seen that film at least 20 times. First few times around (not having read the book) I thought the world of Kubrick; the language is simply phenomenal and gives every appearance of (organic) plausibility. Then finally read the book and it became clear that for once Kubrick was actually riding someone else's fast moving coattails. That is a must read book.

(Speaking of the film: have you noted that there a just a 2 'individual' characters in that film and the rest are 'repeated patterns'?)
