First I saw the movie, then I read the script, and now I've read the book, which is in a nice reverse chronological order. It also provides an opportunity to contemplate upon the differences between the movie and the book.

First of all I'd like to make it clear that I enjoyed the movie when it came out and thought it was great. I thought it was remarkably free of Hollywood cliches at the time. But now that I know what was changed from the book I see they made all the usual changes. These include changing all the fat women to non-fat women, changing all the normal-looking women into sexsymbols, and instead of a dignified ending in the book with just a hint of Rob getting his life together, he's running his own record label in the movie. So, all the usual cliches. Not all changes were for the worse, however. Dick meeting his girlfriend in the movie fit the character perfectly and was way more enjoyable than the "Oh I met her through some friends" letdown in the book.
