Yeah, typical poor show that they put out these days. So many are padded out by endlessly summing up what they've already said every ten minutes, and foreshadowing what they're going to say the rest of the time. Cut all that out and you have a twenty minute programme.
And why were they trying to "prove" that these characters were the inspiration for Indy, as if that in itself was some kind of Holy Grail Quest?
Hopelessly muddled rubbish. Why not just make a show about Chapman Andrews and a show about the German fellow? Why this desperate need to hang it all on Indy? (As if Indy is a legend from Medieval times whose origins are lost in the mists of myth, like King Arthur or Robin Hood: It's no mystery, S. Spielberg and G. Lucas invented him!) Fair enough to point out the similarity, but to labour the point so much? Mindless.
