This episode of "Kolchak: The Night Stalker" is about some weird American Indian character, the 'Diablero'. It (Richard Kiel) appears and disappears along with his friends, a coyote and a crow, in order to steal jewels! This notion sounds so ludicrous that I just assumed the writers for the show were doing drugs or just did this as a joke. I was shocked when I researched a bit and saw that the Soroan Indians DID have such a legend--an evil man who uses the forces of darkness to do exactly what the Diablero does on "Kolchak". Who would have thought?!
So is it any good? Well, yes and no. Yes, despite the story sounding silly is was enjoyable. However, like just about all the shows, it is 100% formulaic and you could see why the series only lasted one season. Kolchak identifies the problem, no one believes him, the police harass him and, ultimately, he destroys the creature while nearly getting killed. Formula...so no surprises with this one.
