I enjoyed this, although as others have noted, it is a bit over the top with the mediocre journalism. For comparison, it is somewhat better written than The Skeleton Crew, a similar book, which was just awful.
Interesting subject and some details I had not read elsewhere. For whatever reason, Frank Bender's sexual proclivities are often emphasized in discussions of his work. I imagine, to give a picture of the whole man, ie, make him 3 dimensional? At any rate, I am glad Mr Bender's vice ran to sexual escapades, and not drugs or alcohol, as we might never have seen his work.
Well worth picking up a used copy, which is not really true of The Skeleton Crew.
