Michael Mann is a serious and admirable director whose work has always been distinguished by a commitment to visual expression. This probably seemed like a good idea – an exploration of computer hacking after a near-disaster at a Chinese nuclear reactor. However the shooting style is as murky as the story with its bizarre tracking shots through tunnels, tedious interracial romance to appease an Asian audience and a frankly uninteresting hero (Chris or is it Liam? Hemsworth) taken out of prison to effect the wishes of the plutocracy. This barely stands up to a single viewing. What was Mann thinking???
