They've shown series several times in past 5-7 years - and their commentator is steeped in the arcanery, clever - and not too full of himself. This station is extraordinary; they actually scour the planet for odd and (to me at least) interesting series - this entirely apart from the nornmal PBS fare. I subscribe - and I'm 100 mi away (with Super Yagi and LN-cooled SQID detector...)
In between we get bio factoids about the difficulty Mc Goohan had.. in selling something not interchangeable with the usual "Sci-Fi" pabulum. Seems he even split with original director for.. his veering much more into the philosophical than per original sketches. Apparently couldn't interest any of the usual suspects in more than one season.
It's certainly worth a re-view in these deadly dull Aschroftian Times.
