Ex Machina isn't unique for its plot but rather, it is an exceptional discussion on subconsciousness. Nathan (Oscar Isaac) marvelled at Jackson Pollock's painting as an unrepeatable feat that is only concocted purely by instinctual hand movement while in contrast to AVA (Alicia Vikander), the artificial intelligence, doesn't possess that subconsciousness and only imitates or conducts herself based on her programming and objectives.
However, possessing the human instinct would mean that Caleb (Domhnall Gleeson) is prone to the faults of subjectivity. As all humans do, Caleb submits to temptation and believed in the idea of love with a conscious machine.
Unlike AVA's creator, Nathan, who joked that he was god, objectivity and negation of feelings rendered AVA faultless and efficient. AVA couldn't paint like Pollock but she could replicate the immense amount of human database in her programme to be the perfect counterfeit.
Ex Machina plays down the self destruction of human nature into an enclosed scale but offers a subject of intellectual magnitude.
