The problem with “The Prisoner” was most of the series content was Allegorical (as was the ending) , and american main stream viewers really didn’t ‘do’ allegorical.
Allegory - a representation of an abstract or spiritual meaning through concrete or material forms; figurative treatment of one subject under the guise of another.
The whole series dealt with society and government controlling people’s lives and the many ways it does.
Add a European bent ontop of that.
But I loved that Lotus Super Seven, whatever it stood for.
Always interested me that the consummate MI6 agent, John Drake, was olayed by a guy born in Brooklyn.
