Query: A great espionage soap opera

I've seen the entire series and have off-the-air copies of all but two of the episodes so I refresh my memory of how good this series is often.It's very well written and well performed. The production values are somewhat lacking and some of the political situations described sometimes stretch believability even with what we know NOW about how things were in the late 1970s. Nevertheless, the show is immensely entertaining and the plots are thorougly gripping.
