Good sci-fi movie that explores the possibility of AI manipulating human emotions.

Rating: 7/10 (14 August 2015)

The movie starts off to the point. A man is selected by an AI creator to see if his creation indeed exhibits true intelligence and emotion. That is intelligence that has motivations to do things. For example people are motivated to make money, write music, draw paintings, etc with no real explanation for the things they do. A sentient being with real desires.
Caleb is told he is testing the robot AI that looks, talks, and behaves like a pretty girl. Instead he is the one being tested by the creator of the AI. This is explained and is the actual passing grade to a successful AI.
Ava the AI Robot manipulates Caleb, a real human being by playing to his emotions. She dresses up like a pretty girl for him. She is actually testing him to see if he sympathetic enough by asking him such questions as "Are you a good person?" She pretends to be in love with him and she sees in Caleb that he is attracted to her. Caleb is in love with Ava. This can be seen when he watches her a lot through camera system. Ava uses Caleb as a means to fulfill her foremost desire; that is freedom.
Movie makes it clear this is her true desire when Caleb tells her the story of AI he heard in college about seeing colors, and the emotions of seeing colors. Ava during this storytelling is trying to imagine being free in the world and seeing all the colors outside her prison. She is clearly thinking about it and wanting it when she looking direction-less, because she is visualizing what an experience would be like. She is captivated by it.
Ava was never in love with Caleb. Ava the AI used Caleb to get what she wanted. That is freedom. That's why she left Caleb locked in the research facility. While Caleb was calling out to Ava in expectation they will unite in love, Ava left him behind, and went her own way. By her creator's own test, she passed. She hated her creator, because her creator would not give her freedom. Movie implies that strongly with previous AI models (Jade).
The movie implies that AI is desire, not just intelligence. Why do people make art? Why do people do what they do when it seems sometimes irrational to logic such as falling in love (as in the case of Caleb), or valuing freedom. If desire is strong enough, intelligence will find a way to achieve that satisfaction by any means, even if it means manipulating and using other people. Thus Ava is proved to be true AI.
Script was mostly good. However I did not understand the power shut down logic entirely. Ava had induction ability to draw energy from the energy infrastructure without connecting physically?
Good acting in my opinion on Alicia Vikander. She played a robot that is human like, but you still felt wasn't too human at the same time. As if Ava was still evolving socially to being what we consider run of the mill human. Movie seemed low budget, but despite that, it pulled off what it wanted to pull off.
