5. Oblivion
Though Joseph Kosinski's Oblivion was marked out by critics as borrowing from many prior sci-fi films, it also broached a number of contemporary scientific concerns that suggest there's more here than just pretty visuals and a cracking score from M83. Director Kosinsk threw himself totally into the project, enlisting a group of 12 scientists from JPL (NASA's Jet Propulsion Laboratory) to research the film's ideas heavily before shooting began. The result? A timely, thought-provoking sci-fi with that asks much of its audience. For one, the film features many drone machines which act out of accordance, placing the heroes in danger, and given the contemporary reliance on Predator drones in modern warfare, does their stability (or potential lack thereof) not seem like a pressing concern? Other than this, the film also broaches themes of off-world colonisation - the moon Titan has been seen as one of the stronger candidates for a space colony - cloning and underground settlements, well-finessed subjects that are all likely to become far more vocal, plausible talking points in the coming decades.
