This book should not have been labelled with "Halloween" at all. Nothing in this has to do with the holiday, celebrations, the date, dressing up, or other things you think of with Halloween. It's got horror, murder, and a few decent Lovecraft elements, but it should have been labeled "horror" or "madness" in its theme.
The Lovecraftian stories are amusing- one set in ancient Rome, one a (sadly) dated technology story (but all these were written in the 1990s, so a lot of it is dated.) The 'deep south' Cthulhu story is terribly amusing.
The only story that really stood up was "Words and Music" by William Sanders.
Several of the others were kinda 'WTF was that?'' and even staring at the table of contents just now, I couldn't remember what they were about.
