Silly... Drifting UP a river? Oh.. And down again? Discovering 'ancient' pottery? Oops we're out of food? Oh this must be Brian my son? Piranha eating the crew? Attacks by wild natives? Could this be any more ridiculous? Turned it off. Not worth even trying to get through. And there were still more than two hours left to watch... Amazon must be throwing money out trying to compete. Miserable fail.
