Sorry I can't supply much detail from my long ago viewing; also, I recall the series at the time being entitled "Counterpoint". I don't believe the series has been re-run under either name since those initial showings. But I do still have a distinctly favorable impression from those early years and remember looking forward to the series weekly. Each installment was a self-contained story, and I believe strove for ironical endings, a big attraction to me during that particularly bland period of TV programming.
Take a look at the featured cast; it's outstanding. I recall being really impressed by John Doucette who didn't look or sound like a Hollywood actor. But there are a number of other notable names, suggesting someone in production with a sharp eye for talent. Anyway, I'm glad to return a favor to the show, even after so many years.
