Great film. The three hours passed easily with no unnecessary scenes, amazing sound, cinematography and profound and gritty visual effects. Love the shifts from color to black-and-white, that at first appeared to be about timeframe, but then was about perspective. Incredible cast. Great script. Great experience on IMAX. Always too loud in theaters, but you fear the silence and then feel the blast. Love the complexity of multi-dimensional characters that are beyond the reach of Hollywood's simplistic touch; so much interpersonal conflict and turmoil make it all less black and white... except that what happened... was black and white in reality and in the movie. :)
