I've been watching this show a lot recently. I liked it as a kid, but didn't know the history of, well, anything. It was funny, Hogan was cool and it was an acceptable sit-com to watch before or after the cartoons that were on. I never gave a thought to why the premise might be objectionable to some people; after all, Hogan made the Nazis look like chumps in every episode. It all worked from a kid's perspective.
It kind of disappeared from the airwaves after the mid 80s, but thanks to MeTV and other such free stations older shows are making a comeback and this is one of them. MeTV airs two episodes a night and I still really enjoy the show. The cast and writing are what makes it work, not the silly premise. Comedy in a POW camp...
I'd love to have heard the pitch for this show, though. In this first season there are a few good stories that also have to do with family loyalty, and several barbs that take sharp aim at the fascist rule of the Nazis. I was pleasantly surprised at that edge. It will be interesting to see how that aspect holds up.
The cast is very good, and it's pretty diverse for a 60s show. It's got me enjoying the show quite a bit.
