When I watched this as a young kid, I had no concept of WWII or the Nazis. So I just watched and enjoyed it. However, as an adult, it is kind of tasteless to do a sitcom about POWs at a Nazi concentration camp.
But on the other hand, they did make the Nazis into cartoonish buffoons.
It is what it is. I'm still on the fence about the tastelessness factor, though.
