According to Kosinski, Oblivion pays homage to science fiction films of the 1970s.
In 2077, Earth has been ravaged from war sixty years prior with an extraterrestrial attacker. The Moon was destroyed, causing earthquakes and tsunamis, while humans allegedly used nuclear weapons for a costly victory.
Humanity is now relocating to Saturn's moon Titan via the "Tet", a large tetrahedron-shaped space station. On Earth, Tech 49 Jack Harper (Tom Cruise) and his partner and lover Victoria "Vika" Olsen (Andrea Riseborough) are among the few humans left on Earth.
Stationed at Tower 49 in former northeastern United States, they are instructed by mission controller Sally (Melissa Leo) to protect the gigantic offshore fusion energy generators, which are generating power for the colonists on Titan, from attacks by Scavs, a small force of marauding aliens who remained on Earth. The generators are protected by both Drones and Jack's regular reconnaissance from his ship.
Despite having had a memory wipe, Jack experiences visions of being on the observation deck of the Empire State Building before the war with an unknown woman. When not on patrol, Jack secretly spends time at a small lake-side house he has built.
There is a scene in which Jack secretly deviates from the mission and re-routes to his lake-side house, reading books, playing basketball and listening to music down there.
Before he sleeps on the grass, he speaks to himself, "I'm gonna miss this place. It would have been great."
What is this "It would have been great"?
Does he suggest that it would have been great if he could go and leave there at will?
If so, why not say "it would be great"?
