Review of Tinker Tailor Soldier Spy

I've belated become a John Le Carre fan. I think this film captures the atmosphere of the books, especially the shabby interiors of the intelligence agency premises and safe houses. I liked the acting, but somehow I literally lost the plot - I couldn't figure out what was happening. I read the Wikipedia article about it, and realised that I'd fallen asleep and missed a major section, which might have made it easier to follow.
