Whether I’m being glib or not, Edge of Tomorrow has been graced with an intelligence that makes such readings more than idle or perverse. Source Code teased the military-industrial complex into the time-warp formula; but never, to my reckoning, has it been allied with the notion of “endless war,” or the trench-war futility of World War I, which the writers (Christopher McQuarrie and Jez and John-Henry Butterworth, from a graphic novel by Hiroshi Sakurazaka) overtly cite. Their intelligence finds a rare partner in optimism—a disposition that has become largely, perhaps systematically, outmoded in the summer-blockbuster form—and which possibly accounts for the blammo cyberpunk D-Day reenactment. In a way, the film is a superhero origin story on themes from Malcolm Gladwell: a spray of gunk spurs Cage’s change from weasel to warrior, but it’s the 10,000 hours of boot camp he gets from Rita (Emily Blunt) that makes him an authentic hero.
Rita is the Morpheus to Cage's Neo, but has to be reminded of this each time he resets the game clock. Rita used to have Cage’s power to relive the previous day every time she died in battle; the aliens have used time travel as their secret weapon all along, but inadvertently surrender their control over it whenever they bleed on an opponent. With each resurrection, Rita learned from her mistakes; this led to her winning the home team’s only victory, as well as the monikers “Angel of Verdun” and “Full-Metal Bitch.” But once she lost the power, which is undone by transfusions of measly old human blood, the ball was back in the aliens' court. Blunt gives Rita substance; she challenges Cruise, and the pathos might have been overwhelming had Cage not been shaped to his persona, and made to give off the vibe of a marketing guru who lives to give TED talks. Cage is at a perpetual disadvantage because Rita’s default is to be dismissive of him, and he’s a stranger after every reboot. Damaged by her own failures, she’s too focused on the mission to notice, as we do, how weary he is of watching her die.
