Owen Gleiberman Chief Film Critic“Free Guy,” starring Ryan Reynolds as a minor character in a video game who breaks out of his drone existence, is one of the fizziest movies you’ll ever see that has a bona fide brain. At first, it may remind you of a lot of other films — it’s like “The Truman Show” crossed with “Ralph Breaks the Internet,” sprinkled with “The Lego Movie” and “Groundhog Day.” But it turns into a rollicking, candified head trip.
