It's the year 2077, and following an attempted invasion by an alien race known as Scavengers, the Earth has been left a post-nuclear desolate wasteground. The few surviving humans have upped sticks to a colony on Titan, leaving only Jack Harper (Tom Cruise) with the WALL-E-esque task of maintaining what's left of the planet, with only colleague/lover Vika (Andrea Riseborough) to keep him company. Jack, however, is troubled by a strange dream-memory, and a startling discovery causes him to question the nature of his mission and the chain of command that has issued it. As with director Joseph Kosinski's previous film TRON:Legacy, this is a visually rapturous piece of sci-fi worldbuilding, but suffers with under-drawn characterizations and naggingly derivative plot machinations.
