There are plenty of movies out there about robots being used to police cities, but "Chappie" is special. Set in Johannesburg, South Africa, a British scientist is tasked with building a robotic police force, but he's equally interested in seeing if he can imbue his creations with human emotions. Despite being warned by his superiors to stop his experimentations, he creates Chappie, a child-like robot with the ability to learn. At first, Chappie is innocent, but when a small gang takes him in, he learns how to use weapons, feel love, and eventually even experience rage. By the end, Chappie's internal life is every bit as complex as any human's, proving that you can't have humanity without experiencing pain and loss.
