Lush photography, glossy visuals, a few iconic fragments of stories, barely any dialogue, a series of disjointed acts of heroism and desperation. All made looking beautiful but not enough to make a piece of cohesive narrative. Some of the usual Nolan's tricks (the different time speed at which the three sub-plot threads unfold) do not save the day. Historically it does not convey the scale and succes of the rescue operation, emotionally it does not engage; there was no much left that could be accomplished except the self-pleasure of cinematic onanism.
