Science fiction films are unique in that they tend to be either big budget spectacles, or quieter character-focused tales that use science and technology to make an argument or observation about the world in which we live. Never Let Me Go is one of the latter. The 2010 film based on the novel by Kazuo Ishiguro doesn't feature any of the hallmarks of what typical moviegoers think of as science fiction. There are no spaceships, intergalactic chase sequences, or alien monsters that come to wreak havoc on Earth. Instead, director Mark Romanek (One Hour Photo) and screenwriter Alex Garland (Ex Machina) choose to focus the film on the emotions of its characters to create a somber (and heart-wrenching) meditation on grief, acceptance, and whether we actually have control over our fate — not to mention an incredibly interesting use of clones as a metaphor.
