An unexciting spy movie

Rating: 5/10 (29 March 2012)

This movie tinker tailor soldier spy is about a British spy agency that got wind that there is a double agent in their midst. The problem is how to find him.
In some movies you can guess the villain because he is played by a famous actor. But in this movie, all the usual suspects are played by more or less famous actors.
This is not a spy movie like 007. There are no action fights, car chases, etc. It's more like watching a drama. What makes it worse is many unfamiliar characters are involved, and the timeline is sometimes played out of order. This all makes it hard to follow the plot. Halfway through the movie, I was bored, and I stopped watching. Admittedly I have poor short term memory. YMMV.
