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.
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.
