Tinker Tailor Soldier Spy 
J.C. Chandor did it last year with his Margin Call and now, director Tomas Alfredson and screenwriters Peter Straughan and the late Bridget O’Connor manage to do it again: making me feel incredibly stupid. Tinker Tailor Soldier Spy is dense and complicated. These days, I don’t have much time on my hands, so instead of watching the film two or more times to fully understand every plot point and twist, I took the easier (and shameful) route: pausing the movie and checking its Wikipedia page every time I got lost (which was often). The horror! But, aside from being pretty much indecipherable, Tinker Tailor is visually arresting. Cinematography, art direction and costume design are all top-notch. But even more impressive is the cast: Gary Oldman leads the pack in his understated, Oscar-nominated turn. Colin Firth, Tom Hardy, Toby Jones, Mark Strong and Benedict Cumberbatch complete one of the best ensembles of the year.
