Gates must be one of the more personable hosts on TV today. The premise is basically the same as his former show Destination Truth on SyFy; insofar as as with Destination Truth the show starts with some spurious rumour and homemade 'newspaper article' relating to some 'lost' artefact or place (as opposed to a mythical creature in DT) followed by Gates heading off around the globe in search of the artefact or place, followed closely by Gate's goofing around while he gets down on the the more serious track of the legends, which he then hunts down in the most annoyingly melodramatic ways possible.
All in all while the content is hokum in the extreme, overly melodramatic in parts, as a travelogue to some pretty interesting places conducted by an intelligent, well travelled, funny and entertaining host.
