I started to watch it and the standard format of somebody who puts together a 'crack' team of investigators to get to the 'truth'. And what do they discover so far? That the Nazi's took off for Argentina. That documents have been forged, tampered with, destroyed, or hidden and what do they reveal nothing much really. Welcome to history.
As far as the Nazi's go I'm more concerned about the real life ones festering in the country and the world. Hitler's dead. Whether he died a suicide or of old age after living in Argentina is irrelevant. The fact is he's very much alive in white supremacist groups everywhere they exist and they need to be stamped out.
