Most critics welcome Ex Machina as an intelligent, unsettling science-fiction thriller, praising Garland’s controlled direction and the tension generated by a small cast in a confined setting. Praise centres on Alicia Vikander’s Ava: the reviews repeatedly single out her precision, ambiguity and ability to make the android more compelling than the humans. The visual design also earns strong notices, while many critics find that the dialogue and shifting power dynamics give the questions about intelligence and desire dramatic weight.
The disagreement concerns how much the story delivers beyond that setup. Enthusiastic reviews find it taut and philosophically rewarding; more reserved responses point to predictable plotting, thin emotional engagement and a loss of momentum. The Evening Standard offers a notably harsher assessment, seeing an overstretched short story dominated by male fantasy. Even among supporters, there is some doubt about whether the film’s ideas remain as persuasive as its performances.

Garland's directorial debut is his most successful and satisfying creation yet, an old-fashioned grown-up sci-fi executed with Kubrickian scrutiny and a darkly satirical pulse. Vikander's poised, precise performance as Ava stands out as the star, crafting both a sci-fi and feminist icon.

Garland's cerebral directorial debut questions what it means to be human through philosophical debate and tense interactions in a confined, beautifully rendered setting. It is seductively strange, consistently thought-provoking and admirably adult, even if somewhat predictable.

Garland's AI thriller feels like an elegant short story bulked out to feature length but handled with confidence. Vikander steals the movie with a sly dreaminess in the central role.

The debut is more compelling as a study of millennial tech entrepreneurs than as pure AI speculation, with a classical setup that reveals its plotting too readily. It discusses the morality of AI in depth but ends up fudging its stance, though the ambiguous climax is satisfying.

Garland's art-house debut takes viewers to the birth of convincing AI in a slinky, thoughtful setup with strong dialogue and Vikander's spellbinding presence. An obvious twist and clunky developments undermine the credibility of a story that promised more.

40*
An elegant variation on Frankenstein that turns Gothic and predictable, over-extending a short story into a chamber piece focused on male fantasy and a foxy female robot. It follows in the wake of stronger films like Her and Under the Skin without matching their challenge.

Garland's directorial debut rejuvenates familiar AI themes by crossing them with Moreau-like exploitation of artificial beings, delivering a timely, sharply paced chamber piece whose sympathies ultimately lie with the android. Vikander's sensual performance as Ava stands out amid the tense power dynamics and uncertainty about consciousness.

The critic praises the stylish directing debut, sleek production values and visual design centered on the android Ava but criticizes the third-act slump and lack of dramatic punch or fresh ideas. It is called a classy piece of cerebral sci-fi that functions as superior pulp for fans despite feeling flimsy.

The review describes the directorial debut as a brittle, beautiful, witty and sensual digital-age Frankenstein that slyly examines gender and humanity. It singles out Oscar Isaac’s nuanced, funny portrayal of the tech mogul Nathan as a highlight alongside the exquisite design and performances.
Read the full review →The critic notes the film starts with an original premise and marvelous design for Ava but quickly turns formulaic, shifting to a noir-ish plot about abusive masters and wily slaves rather than exploring unique singularity ideas. Ava remains a creepily alluring highlight thanks to Vikander's performance.
