Microsoft is back with another weekly $5 movie sale. For this roundup, our top pick is I, Robot which fetches $15 at Google Play right now. This epic adventure stars Will Smith as a “robo-phobic police detective” that’s investigating the apparent suicide of a robot designer. Through the course of the movie, he runs into a prototype robot that has human emotions, but is that enough to save the world? You’ll have to watch and find out. Rated 4.3/5 stars. Not a robot movie fan? Well, there’s plenty more on sale below, as well as at Microsoft, including classics like Home Alone 2: Lost In New York, Happy Gilmore, and many others.
