The Earth of 2077 is desolate after a conflict with the alien Scavs. Jack (Tom Cruise) and Victoria (Andrea Riseborough) are an 'effective team' who are on a salvage mission and are due to return to their colony on Titan soon.
Jack maintains drones that patrol the enormous hydro rigs that convert the dregs of the ocean into a viable resource for the surviving human race. His private time with the elements and a close and dangerous encounter with the Scavs, however, forces Jack to re-evaluate everything he takes for granted.
Oblivion is a very satisfying science fiction movie, which shares similarities to previous endeavours in the genre. The clean and shiny aesthetic of Jack's craft and firearms as well as the score are very similar of the Mass Effect style; Jack's appreciation of nature, especially when he nurtures a tiny plant, is reminiscent of Silent Running; and the daring act in the finale shares the philosophical side of 2001: A Space Odyssey and a hint of the action of Independence Day.
Fortunately this film does not leave the viewer with too many questions (unlike Prometheus) and provides enough clarity to enjoy the experience. For those in need of an action-packed sci-fi hit, see Oblivion.
