A pleasing throwback to an era in which ideas powered movies more than special effects, sci-fi action thriller In Time makes literal the scramble of underclass day-to-day existence, telling a story wherein everyone ages only to 25, and thereafter survives or perishes by trading on one year of allotted time, which is the currency of the world, and marked by a green countdown clock on their arm. Providing a steady flow of lively entertainment due in large part to the brain-tickling nature of its central conceit, the movie benefits from a superb below-the-line team that gives it a certain stylishness and nice production value, even though budgetary constraints obviously influence some set-ups. In Time only runs into trouble when attempting to service some of the more whiz-bang elements of its fight-the-powers-that-be plot, instead of taking a honest swing at something more subversive or transgressive.
