Dwayne Johnson in G.I. Joe: RetaliationG.I. JOE: RETALIATION

If you handed a box of crayons to a group of eight-year-olds with action figures, they'd probably come up with a more entertaining storyline for G.I. Joe: Retaliation than the one we're stuck with, which is your standard blockbuster nonsense about a megalomaniac's plan for world dominion and the crack team of well-armed, quip-ready hotshots attempting to thwart him. In a welcome surprise, though, director Jon M. Chu's follow-up to 2009's G.I. Joe: Rise of the Cobra is, unlike its forebear, quite a bit of zippy, throwaway fun, a fast-moving and happily unpretentious diversion with jokes, and good ones, obviously written specifically for viewers well over the age of eight.

Justin Timberlake and Amanda Seyfried in In TimeIN TIME

Set in either the distant future or some Bizarro World version of the present, Andrew Niccol's sci-fi thriller In Time imagines an Earth in which time is literally our universal currency; an eight-hour work shift can add a few days to your life span, but a trip to the grocery store will cost you two weeks. (A slowly ticking, neon-green clock embedded in your forearm tells you just how much time you have left to spend.) It's also an Earth in which humans have been genetically engineered to stop aging at 25, and are then allowed one year more before their bodies shut down completely ... unless, of course, they have the proper means, or the proper lack of morals, to buy or steal as much extra time as they want.
