Not a patch on the Series

Rating: 3/10 (6 August 2019)

Gary Oldman as George Smiley very good, but not a patch on Alec Guinness.
Percy Allerline, a character that could hold his own. Toby Jones, as good as he is as an actor could not pull off that "Alleline is presented as a bombastic bureaucrat full of low cunning and intimidation, with a distinctive turn of phrase." (From Academic Wikipedia).
They mispronounced Esterhase, badly done, indeed
Kathy Burke could not pull off Connie Sachs. Beryl Reid from the series was superb. "I love the Circus & all my lovely boys" why make her swear??
All in all it completely failed in my estimation, being a fan of the series.
