The plot: In a distant future, a ravaged, trash-strewn Earth has been abandoned by its most elite residents, who enjoy lives of pampered privilege on a gigantic, tricked-out space station. But there's life on the blue planet yet as they'll discover when one brave, soulful, robotically enhanced ground-dweller fights his way onto the floating paradise.
Sounds a lot like... Wall-E (2008)
Too close for comfort? Pretty bad but not quite as blatant as Oblivion, which echoed that basic premise, then added EVE-like drones and a Wall-E-esque glorified janitor as its protagonist.
