Dave Sim had a great take on the show. It's a satire of the then-current corporate mindset/environment. The shows Nazis are basically men the grey flannel suit.
Schultz is the beleaguered labor class. Klink is clueless middle management. Burkholder is the tyrannical upper management. SS Major Hofsteader is the dreaded outside consultant (sort of a precursor to Alec Baldwin in glengarry Glenn Ross).
Berlin is the home office and the Russian Front was unemployment.
Interesting take..a funny show. I am Jewish and not offended...much of the cast was jewish..
...as was Bernard Fein, the show's co-creator.
There was a really well done (IMO) fan fiction that wrapped up the series and talked about the aftermath.
For the life of me, I thought the show did have a proper ending. Wasn't there an episode where they learned the war was over and the three main characters (Hogan, Klink and Schultz) ended up having a drink in Klink's office, discussing going back to civilian life...with it turning out that Schultz was actually the owner of a giant toy company and was probably going to end up being Klink's boss?
