The movie celebrates the idea of the hero as someone who demonstrates courage, integrity, and perseverance, believes in something greater than him/herself, and stands up for those who can't stand up for themselves. Self-sacrifice, friendship, and loyalty are also key themes. There's a very pro-America message, which is reinforced by the strong patriotism of the 1940s setting. Although Captain America at one point professes a reluctance to kill people, he and his soldiers don't have any qualms offing tons of bad guys or using violence as their main means to solve problems.
Positive Role Models & Representations
Frequent strong explosive action violence and weapons. Buildings, vehicles, and more are engulfed in fireballs; lots of gun use. A villain known as Red Skull has a monstrous/skeletal face that could be very scary to younger kids. The bad guys are developing super weapons powered by a mysterious energy source; they're extremely powerful, and some can completely vaporize people. Characters are killed, many impersonally/mostly bloodlessly in gun fights and big explosions, but a few (including some we care about) in more upsetting ways -- a couple are shot point-blank, and one goes through a propeller (blood is spattered). Car and motorcycle chases, fist fights, and war imagery. A child is held hostage. A character commits suicide rather than be captured.
Some flirting and a couple of kisses; romantic tension between two main characters. Soldiers ogle a woman when she wears a pretty dress. One implied mooning by a soldier; several scenes with Steve/Captain America shirtless.
Several uses of "hell," plus very infrequent use of "ass," "damn," "son of a bitch," "oh my God," and British slang like "bloody." Some insults, like calling soldiers "ladies" to demean them.
Tie-in to vast quantities of related merchandise.
Ease of Play
Dr. Erskine drinks some schnapps; he later implies that he had too much, but he's not shown drunk. Soldiers drink beer (and harder liquor) in a pub/bar; one is a little tipsy. Captain America tries to get drunk but is unable to.
