Our take on Ex Machina
Alex Garland's chilly 2015 debut confines almost its entire drama to a remote mountain retreat, where a young coder is invited to test whether a reclusive tech billionaire's humanoid AI can truly pass as conscious. What unfolds is a taut chamber piece of shifting power and mounting suspicion, science fiction told through conversation rather than spectacle. The film thrives on ambiguity, letting questions of manipulation, desire and control simmer without easy answers. It suits viewers who prefer ideas to explosions and who enjoy a slow-burn psychological unease that lingers. Come for the sleek premise, stay for a mounting dread about who is really testing whom in that glass-walled house.
