This series explored various phenomena, legends, and mysteries and still holds up 20 years after it left the air. I just loved this show as a grade schooler in the seventies, because I was heavy into monsters and ghost stories and the show frequently profiled legends like vampires, werewolves, Bigfoot, the Loch Ness monster, and it did introduce me to subjects like the Hope Diamond, the Mary Celeste, and the burial of Pompeii by Mt. Vesuvius' eruption. While hardly authoritative(the History Channel disclaimer informs viewers that the show is primarily conjecture), the show is intriguing to watch now. Leonard Nimoy's calm, detached narration is comforting in a nostalgic sort of way, and the entire show has a resolutely objective feel. Funny, but I thought the show only lasted a couple of seasons, not the six indicated. Oh well, the show must have alot of fans, because it has run on A&E and now resides on the History Channel. Lucky us!
