Common Sense Note
Parents need to know that this relentless action adventure inspired by the '80s cartoon/toy line is filled with extreme (albeit minimally bloody/gory) violence. Kids will want to see it because they're the ones who play with the toys, but there's no end to the parade of characters who are slashed, stabbed, shot, or dispatched in various other ways. (Unlike in the similarly inspired Transformers movies, most of the victims here are people, not machines). There's also a lot of potentially scary medical imagery -- needles, scalpels, painful-looking procedures, and more -- and some intermittent strong language (including "s--t"). Hasbro, the company that makes G.I. Joe toys, co-produced the movie -- meaning that the story doesn't contain product placement so much as the product placement contains a story.
Some kissing, cleavage, and discussion of "touching."
Constant extreme -- though generally bloodless -- action violence. A man has a white-hot metal mask affixed to his face. Characters are shot, decapitated, and stabbed and slashed with swords and throwing stars. Characters fight both hand-to-hand and with firearms, and there are intense martial arts sequences. People fall from great heights. Planes, ships, and other vehicles fire on each other with a plethora of weapons and missiles. Lots of general mayhem and destruction. In flashback, children engage in brutal violence involving frying pans, flames, martial arts weapons, and more. A child murders a teacher -- it's off-screen, but the body is seen. Surgical imagery.
Some strong language, including "s--t," "bastards," "piss," "a--holes," "damn," "hell," "bitch," "crap," "goddamn," "oh my God," and more.
Although the movie theoretically promotes the concept of international cooperation to defeat threats, any true positive takeaway is neutralized by the movie's total divorce from reality and nonstop violent mayhem.
The film is based on a cartoon series that itself was based on a toy line (and the movie was actually co-produced by Hasbro, which makes those toys), so you could argue that the whole thing is an exercise in product placement. Other brands visible or mentioned include Hummer, Mercedes-Benz, Double Bubble, and Cisco.
