This could have been a British Comedy series for all you know!! The level of comedy in this series was much higher than most of the American comedies of the time. This was a genuinely funny and at the same time very controlled in its use of the setup (a touchy subject to joke about).
The sophistication of writing for this series can be compared with "Yes Minister and Yes Prime Minister". The performance of all the actors was always better than average and specially the performance of Werner Klemperer was spot on. There can never be another Commander Klink. I was also a big fan of the performance of John Banner. Bob Crane has become immortal due to just this series and we can safely say that even its reruns are a treat to watch.
