For many kids, G.I. Joes are fun to dismember. It does not matter whether they’re the larger figures, or those tiny ones where their legs and torso are bound by a thick rubber band: the average G.I. Joe toy is a canvas for a kid’s (often sadistic) imagination. G.I. Joe: Retaliation internalizes the freedom offered by the toys’ banality, and sees the universe as an opportunity to expand on a particular vision. I don’t want to get too deep into auteur theory — parts of the film are breathtaking in their inanity — but director Jon M. Chu embraces the gleeful stupidity like an imaginative kid might.
