While i have found many of these shows entertaining, I have never really taken any of them seriously.....even though i believe wholeheartedly that there is probably other life (advanced i hope) in other parts of the universe. Whether they have actually contacted us before now I do not know......and not to surprise you but I have seen and experienced what i have always considered to be a UFO which was a completely amazing experience and is still a mystery to me to this day.......however, why I feel this show fails in its purpose is based on several reasons......first, the premise is flawed to a point that defies logic.....if the Nazis did have some sort of alien and/or supernatural assistance it certainly didn't do them any good.....the allies (including us) beat the pants off them using very conventional means......maybe their aliens were sub-standard as aliens go........secondly, to say that the Germans had invented and utilized all this fantastic superior technology during their war effort is interesting but I have to reiterate that also didn't do them any good either......as a matter of fact it was the German tendency to over-diversify (too many projects going at the same time) that helped defeat them........not as much as allied superior manufacturing, military leadership, perseverance etc but to a degree at least..........while you could say that although their V weapons were interesting in that they were an extension of existing tech of the day, they were more frightening than effective, clearly.
As a matter of fact....from the Norden bombsite and radar to the atomic bomb, if you consider all the advanced technology the allies developed in the war it is clear that we outmatched them technologically otherwise how could we have defeated them so soundly.......one could make a better argument that WE actually had alien assistance........something that no one has ever seriously claimed due mainly to the fact that the creation of our technology has pretty much been an open book as time has passed due to the nature of our society.
Lastly, what makes me most irritated about the bumblers that produce these shows is more of a general complaint about most shows of this genre......simply that by virtue of their rambling tangents, flawed logic and their attempt to connect everything with everything else, they diminish accurate and interesting evidence that is probably valid and they overload any good analysis with tangential conclusions that have more science fiction than science or historical fact.........every round nazi weapon was not based on flying saucers.....they were probably just round, you know?
All in all, they shoot themselves in the foot by under analyzing important and documented history and focusing on myth as a basis for their conclusions and by doing so, do a dis-service to serious historians everywhere......this pattern or modus operandi, causes people to view anyone who does investigate these kinds of historical connections as crackpots "like those guys on TV".
