“The Last Man” (** out of four) was an ambitious but pretentious futuristic melodrama set in yet-another “Blade Runner”-like future in which a war veteran (Hayden Christensen) with PTSD begins to think it’s apocalypse now and joins forces with a visionary messiah (Harvey Keitel) and begins the construction of an intricate underground shelter but this threatens his sanity and the stability of society as a whole. Visually hypnotic at times and has some striking individual scenes but story as a whole is too derivative and lacks momentum. Christensen is stiff in the lead but Keitel is well-cast in a good supporting role.
