Slow paced

Rating: 8/10 (12 January 2017)

There are three main characters, Nathan who owns the world's largest search engine company. He is an acknowledged a genius. He is obnoxious the way he uses his wealth and fame to bully others and treat them as toys. He uses his search engine to spy on everyone on earth. He is a jerk, in much the same way Steve Jobs was.
Caleb is his employee, a talented, pleasant, handsome, young nerd.
Ava is Nathan's AI creation.
All the action occurs in Nathan's high-tech, high-security house hidden miles away from anything in the mountains. Nathan uses electronic key cards to lock people into rooms for his amusement.
Supposedly, Caleb's job is to test Ava to see if she could pass a modified Turing test when he would interact with her face to face.
Most of the movie is either awkward flirtatious getting to know you conversations between Caleb and Ava or Nathan being a prick tormenting Caleb. The pace is glacial. The dialogue is quite non-technical and reasonably sophisticated for Hollywood.
One of the themes the movie explores is how do you know when people/robots are lying to you, and when are people/robots just pretending to like you.
As you would expect, Nathan gets his just deserts, but the movie has an unexpectedly gruesome dark and somewhat confusing ending. It is not at all the happy ending I expected. It left me feeling ill.
