The Lost Boys - Craig Shaw Gardner I don't think I even finished this book.

I like to read adaptations of movies I like because I like to know backstory, motivations, the things the director/editor left on the cutting-room floor (Alan Dean Foster is particularly good at this, and Vonda McIntyre's adaptations of ST-II and -III genuinely add to the stories).

Gardner offered none of these - it was a word-for-word transcription of the script without even an attempt to flesh things out.
