Q: It was recommended to me by someone whom I think beleives in the interdimensional and non-ET aspect of it all. I kept an open mind, but finally came to the conclusion that John Keel wrote a fradualent and contrived story, with an underlying "distracted" attitude that in reality is quite insulting to the reader. The book is probably pure fiction, and if you seek more than fiction, then it is bordering on pure trash. As an "investigator" he poorly documents his findings. Don't buy it, check it out from the library, please.
A:
Negative
