On Saturday afternoons I would watch “The World at War” with its fiery opening. Real serious stuff. I got the full understanding of what WWII was all about, so much so that I do not need to go to the Holocaust Museum in DC to understand the Holocaust.
When I watched “Hogan’s Heroes” was like a bit of needed comic relief.

I find that opening, and especially the music, to be incredibly haunting. I have the whole series on DVD.
