OK....like Mysteries of the Bible, this ruled A&E when I was a little kid. And I was a little kid in the 80s and very early 90s...this came out in the middle 70s so fair warning...some of it is going to be solved and some of it is going to be insanely wrong. Some of the theories put forth are ridiculous by today's standards of science and understanding and unfortunately sometimes it even predicts. BUT....ignoring the dated, it's still an excellent show that served its purpose when I was 8...it scared the heck out of me. And I learned from it so double trouble. It could do creepy, it could do thrilling, and it could do wondrous. All around it's one great show, even today.
