Another 48-year-old whose life was changed by tis show Reading through the comments, I'm struck by how many of us were 12 or 13 the year "The Prisoner" hit television. That's a good age to see it for the first time, I think - not that I'd know otherwise - when you're just on the cusp between childhood and adulthood, trying to be rebellious and conformist at the same time, trying as well to make sense out of a society that, especially in 1968, seemed to be determined not to make any sense. For me, it also helped that Patrick McGoohan was one of my idols - as "Secret Agent" John Drake, he epitomized cool, more so even than Sean Connery.
Someone else compared the series to a good novel (a couple of tie-in novels were published at the time, the better one being by Thomas M. Disch, a prominent sf writer), and I think the comparison is a good one - it's got the depth, the intelligence, the imaginative depth and the sophistication that one expects from good art and almost never gets from a television series. It also has a hearty helping of what I now recognize as British whimsy, a sense of the absurd - change the tone of the direction and that huge white bubble chasing No. 6 around the Village could be right out of "Monty Python," which of course came later. McGoohan, I gather, had to leave school relatively early in his life, and the Village itself resembles the mind of a highly intelligent autodidact: a jumble of strong visual styles, a very individual sense of structural coherence.
What's most impressive about the series, in some ways, is how little it dates. Watch almost any other television show from the late sixties - the costumes, the slang, the hairstyles all swoop you back to a specific period of time and trap you there until the final credits. Apart from a couple of female hairdos, "The Prisoner" makes no concessions to its era. There's nothing to remind you of the "real world," to jerk you out of McGoohan's dream. The final two episodes in particular are beautifully written and, for a television series, almost illegally ambiguous. A good television series these days will often pose the viewer a moral dilemma, leaving you to decide for yourself. It would never make you question the very significance of what you've just spent the last thirteen weeks watching.
All things considered, it's still the best TV series ever aired.
