The Girl with the Dragon Tattoo
Haven't read the book, or seen the Swedish movie, but I saw the one currently in theaters last night and it was awesome.
David Fincher (director) is simply brilliant. Fight Club, The Social Network, now this. Three of my favorites that are really up there. Love his directing style and his choice of scores; his films have that distinct feel.
I don't know if this movie is Best Picture material, but it was thoroughly enjoyable. Very suspenseful. Rooney Mara was outstanding and Daniel Craig put in a good performance as well. It's long and drawn out (but not unnecessarily) and a bit confusing, but I plan on seeing again soon to pick up on the details I may have missed, because there were a lot. It was a rather quick moving film though after the plot was laid out.
Go see it.
