I am a fiend for novelizations. You can get a lot of insight as to what the shooting script might have been, for example, and sometimes some of your favorite writers are slumming it under a pseudonym. It can be an interesting game to guess the author if their prose has enough of a fingerprint and you care to do a little homework after.

Some of them are so good they bring additional life to the original, and buttress flaws -- Greg Cox wrote a trilogy about Trek's Khan that left me delighted with its ingenuity.

Speaking of, I wonder if the villains at Disney still owe Alan Dean Foster a lot of money.
