One character quotes the serenity prayer: "God, grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference." This idea is one of the central themes of the movie.
Frequent comic book/cartoon violence. A boy comes home to find the body of his mother, who was murdered during a break-in. Wonder Woman holds a severed head. She also causes a death by hanging. A character's face is punched until bloody and he is knocked out. A tsunami sinks a ship.
The mother of a superhero asks her son if he's gay.
Some profanity throughout: "a--hole," "crap," "hell."
This movie is an offshoot of characters created by DC Comics and is part of a movie franchise. These characters are also merchandised as action figures, Legos, and birthday-party favors, among other things.
