Raids 'Raiders of the Lost Ark' in nearly every way imaginable, from the time period and search for a mysterious artifact (the titular Gold Monkey) to the two-fisted, leather jacket wearing hero battling Nazi bad guys. It's not like Indy is exactly %100 original, but coming right on the heels of 'ROTLA', 'Tales' does seem like it's definitely raiding Raiders.
Stephen Collins (yeah, I know, me too) is reasonably effective as Wannabe Jones, and a few "Oh, yeah. Him/her!" types round out the cast. The script features the occasional bit of wit, and the production values are above average. The show only ran for one season, but it has developed a bit of a cult following over the years (current IMDb rating is a more than respectable 8.2). The components for a reasonably fun bit of weekly escapism are here in this pilot episode, though I don't quite see it as being a, well, lost treasure.
