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.
