Actually most of the phenomena, artifacts and mysteries in this series CAN be explained, but it's still good fun to listen to Shatner's faux awe and excitement as he explains them. (Remember, he's the guy who thought it was a good idea to recite the lyrics to "Rocketman" while chain smoking on a variety show.) The episodes are interesting, and the research is good, but there really is nothing astonishing about them.
Give it a look, because you won't regret it.
