why all the changes ?

Rating: 4/10 (28 June 2012)

This movie will be a disappointment to any LeCarre fan. There is nothing wrong with acting, totally the opposite, there is very good acting. Great locations, superb photography.
But I don't understand why they changed the story so much. They could have made a new movie, it would have been great. Instead they took 'perfection' and made a rather bizarre attempt to change it.
You will like this movie if you never read LeCarre but if you are a fan who knows the characters very well throughout the decades of reading, this movie is unwatchable.
BBC's Sir Alec Guiness Smiley series did serious and substantial editing also but they did not change the essence of characters and the storyline. Why, why they did this movie ?
