A wonderfully cast adaptation (probably the best as such of Le Carre's work), this is an elegant slow-reveal of a series with nary the need for a crane shot or choppy editing, just intelligently paced drama that doesn't lay all of its cards on the table in the first episode. A good example of what one might call'peak period' BBC where productions were made with integrity & respect for the abilities of the audience.
The new film is incredible, but the late Sir Alec Guinness' portrayal of George Smiley is more accessible and emotive. This series maintains sharp witty dialogue and a dark atmosphere that grabs the viewer from the very start. Pure brilliance.
