This is one of those books that I like the *idea* of, but not so much the execution. It's gotten to the point where if a book has the word "spooky" (or a variation) on the cover, I'm just going to assume it's not. The idea - offering ideas for six themed parties - would make for an excellent book if they were all actually Halloween-themed. Sadly, even the Halloween-specific party suggestions fall a little flat.

Ex Output:
Negative


Ex Input:
Very simplistic writing style- he said, she said, then he said, then she said. This reads like a first attempt, not like a book written by a seasoned author of over 30 books.

Ex Output:
Negative

I like the book just because it was fun to read, but very skeptical about the way the writer admits he had seen ufo sightings night after night in chapter 10 of the book. My question is why in the world a guy like John Keel arms himself with only a flashlight and not a camera. He obviously sets himself up to see strange lights but does not bring a camera to capture the event. Unless he makes a book that has pictures for us to examine, and not hording all the evidence for himeself. Then I will have put him in the "Good story teller" catagory and not a "ufooligist". I must admit I am tired of all the hidden evidence about this matter, and I think we are all ready for the truth. If you want my opinion I just threw all his credibility in the bin. I must admit I really enjoyed this book.

Ex Output:

Positive
