Justice League: The New Frontier

The superheroes are all brave and noble, even as they disagree about how to go about the superhero business. Strong sense of teamwork and mutual respect among the heroes, and these good guys even come through when the public, military, and government persecute them. There's a somewhat negative portrait of the United States in the 1950s as paranoid, homicidally racist, and conformity-ridden. The movie ends with President Kennedy's "New Frontier" speech, which connects the pioneering spirit of America not just with space exploration, but also with confronting and defeating racism and prejudice. 

Blood flows from superhero and mortal injuries, and dead bodies are seen. Opening scene depicts a suicide-by-gun from the victim's POV. In a flashback to the Korean War, a North Korean soldier is shot and killed at point-blank range; not shown, but blood. A dinosaur's head explodes, and monsters get dismembered. A little boy is threatened as a human sacrifice. Wonder Woman makes a reference to rape endured by the women of a village she has just rescued; the women, when freed, take up arms, and the remains of the soldiers are shown in a bonfire. Knife fight. 

Occasional profanity: "Son of a bitch," "tear-assing," "damn," "hell." 

Social drinking, smoking in a glamorous Vegas setting. Drinking in a neighborhood bar. A character announces, "Have a drink, and smoke 'em if you got 'em." Cigar smoking.
