"A rare and welcome exception to that norm."
— Matt Zoller Seitz, RogerEbert.com
"Visually stunning, intellectually provocative, emotionally powerful."
— Nell Minow, Movie Mom
"With a stellar cast and seductive look, Ex Machina is a sleek contraption for capturing our imagination."
— Joe Williams, St. Louis Post-Dispatch
"Ex Machina is a disquieting power struggle waged in terms of human weaknesses, refracted through gender."
— Alison Willmore, BuzzFeed News
"Ex Machina has a precise visual sheen that evokes David Fincher, and earns the sudden, quiet, powerful scares of his best work."
— David Sims, The Atlantic
"The picture is a triumph: it's arguably Garland’s tightest and most fascinating screenplay to date, brought to life with meticulous filmmaking and sensational performances."
— Oliver Lyttelton, The Playlist
"To dismiss Ex Machina as just another robot movie would be like calling the Grand Canyon a hole in the ground. It's one of the most original, smart, thought-provoking science fiction movies of recent years."
— Marc Mohan, Portland Oregonian
"Ex Machina is a spooky piece of speculative fiction that's completely plausible, capable of both thinking big thoughts and providing pulp thrills. But even saying that doesn't do this quietly unnerving film full justice."
— Kenneth Turan, Los Angeles Times
"A riveting sci-fi investigation into humankind's experiments with A.I. (with pages from Spike Jonze's Her and Stanley Kubrick's 2001), Ex Machina marks the extremely able directing debut of British writer Alex Garland, of the novels "The Beach" and "The Tesseract," and of the screenplays for Danny Boyle's '28 Days Later' . . . and 'Sunshine.'"
— Steven Rea, Philadelphia Inquirer
"It plays like Frankenstein meets Blade Runner via Hitchcock haunted by the ghosts of Charles Dickens’ Great Expectations, in a film that’s both highly literate and steeped in tense cat-and-mouse chills. Thematically epic – it demands to be seen at least twice and should fuel hours of debate — structurally it’s as lithe as Ava’s perfect mesh frame."
