This was a fast read.
Somehow the marketing - probably more for the movie than the book - led me to expect something funnier. The official Amazon review gets it right - "harrowing" is more like it. There were certainly some funny moments, and some wonderful turns of phrase, and I really liked the portrayal of the author, with his love of all things shiny. I suppose I can forgive the marketers - if I hadn't thought "funny", I might not have picked it up (after all, don't I have enough depressing stuff to read?), but that definitely isn't my overall impression of the book.
