Caleb(Domhnall Gleeson) who works for the largest internet search engine in the world wins a trip to hang out with the founder(Oscar Isaac) of the company. When Caleb meets Nathan, he finds out he is part of something much bigger. Nathan is in a very secluded and highly secure compound where he is developing Artificial Intelligence. Nathan wants Caleb to perform interviews/tests to see if his creation, Ava(Alicia Vikander), has a conscience.
Caleb is excited for the opportunity despite the odd behavior of his employer Nathan. The interactions between Caleb and Ava were shot incredibly well. Caleb starts to feel things are amiss when he gets into the artificial mind of Ava and his dealings with the heavy drinking Nathan.
Plenty of plot twists keep you wondering what may or may not be real inside this film. Why was Caleb brought here? What does Nathan really want? Can Ava love someone?
On a scale of one to five pile drivers, I'm giving "Ex Machina" four pile drivers. The film kept me interested from start to finish and really kept me guessing.
