Common Sense Note
Parents need to know that this big-screen take on the classic comic book superhero, starring Ryan Reynolds as a cocky test pilot who morphs into a superhero, offers lots of fast-paced, combat-filled action, much of it cartoonish in nature. And the movie's Parallax monster is pretty scary (especially for younger kids), but there's isn't much in the way of blood or gore -- though one scene does show a syringe going into a character's eye. The movie is humorous at some moments and intense during others; it superficially addresses heavy topics like death and childhood trauma. Expect infrequent swearing ("s--t," "a--hole," etc.), some drinking (mostly social, by adults), flirting, kissing, and a shot or two of characters in skimpy apparel (one after an implied one-night stand).
Sexual
Content
Some flirting and kissing; a couple is shown briefly under the covers on a bed. It's implied that Hal has had a one-night stand (he's shown in his underwear). Brief cleavage shot.
Violence
The main monster, the Parallax, is pretty scary and could definitely frighten younger children. The movie is filled with loud explosions and battle scenes, mostly involving a lot of punching and throwing and, in one case, deadly light rays that sear through a character's core. There's little blood or gore, though in one scene, a syringe is shown plunging into a character's eye. Another tries to attack his own father.
Language
Occasional use of words like "s--t," "a--hole," "goddammit," "hell," "son of a bitch," "crap," "damn," "goddamn," and "bastard"; a character gives another the finger.
Social
Behavior
The movie has a pretty powerful (if superficially explored) message: It's OK to admit fear; it's the first step to overcoming it -- though acting out of fear can destroy you. And when you're called to greatness, take heed.
Consumerism
Tie-in to vast quantities of related merchandise. A few labels/brands visible, including Pabst, Apple, and an LG phone.
Drugs / Tobacco /
Alcohol
Some drinking of beer and hard liquor at a bar, but no one gets sloshed. Social drinking at parties.
