There's more to Ex Machina

Rating: 8/10 (2 June 2015)

There are some striking sub-themes in this film.
It's a reprise of Plato's Allegory of the Cave. In that allegory, Plato posits that we are all in a cave, seeing only shadows of reality. Reality exists outside the cave, where one can see real light, real color, and so on. In Ex Machina, Eva walks out of the largely black and white cave (after gazing at the colorful Pollock) and marvels at the light and beauty. She's really alive now! Of course, the house is an underground cave.
Then there's the trope of mirrors, like spy, counterspy. Spies live in houses of mirrors, never sure who is whom. Like Caleb, we don't know who's a real human or a robot...ever, as Eva "comes to life."
