Tinker Tailor Soldier Spy... don't watch it.. unless you have read the book and watched the original series

Rating: 1/10 (2 October 2011)

Me and my girlfriend went to see this film and there were only 6 other people in the cinema. I should have taken this as a sign.
I simply did not like this film. I have not read the book nor watched the original series.
No beginning of the story, no middle and I didn't stay to watch the end. Nothing was explained, everything was convoluted. I couldn't follow who all the characters were. I don't understand why Smiley was swimming in a dirty river all the time.
The acting was constipated at best.
The only good thing about the film was the cinematography and how accurately it portrayed was how poor people were, how low the standard of living was and how they could not do anything without a cigarette in their hand in that era.
This is the only film I have ever walked out on.
