Deletion of Order Castles of the Third Reich

Comment: I cleaned the article some and you can see the original format https://en.wikipedia.org/w/index.php?title=Order_Castles_of_the_Third_Reich&oldid=690441592 here, but I was unable to find anything that covered the documentary itself. Offhand the sources appear to be about the buildings/facilities and not the film and since notability is , the best we could have here is a redirect to the director's page. I will say that the director's page will need some cleaning, as it looks like it was written by a PR person

Comment: If this is kept, it will need to be extensively pruned to remove the long sections discussing the history of each section. While I'm aware that they're the focus of the documentary, going into depth about each location puts  weight on the topics. Actually, I think that I'll clean this up now
