A great series.  Emma Peel (Diana Rigg) was and still is the sexiest of the female martial arts heroes before or since.  Patrick McNee was in real life not too dissimilar from character John Steed but he never matched his work in this series.  Low key, tongue-in-cheek funny, pretty non-violent, and still remembered and revered today, it should be a model for TV and movies today in lieu of the pseudo-scientific, over-the-top special effects stuff we get instead.
