You know. When you are dealing with a complex writer like LeCarre, you are going to get a complex movie. Unfortunately, to the casual viewer, there's an awful lot that is going on that is grounded in the long dark past. While the story of the search for a mole in the network is a valid pivot point, there are so many intricacies that you are left to guess. Perhaps I am not that bright, but I need a bit more. I guess the question is, do I need a George Smiley playbook or a stack of books to follow this film. If that's the case, how many people can appreciate this? The time period in issue is really in the fairly distant past. I have to agree that so much of what we see is really dumbed down, but when the plots are so slowly developed and depend on so much inside stuff, even the astute viewer is left in the lurch. It isn't that I didn't like it. But I may have to give it another shot to really appreciate it.
