Plenty of strong messages about women's ability to be skilled warriors/fighters, the importance of teamwork and communication, and the various ways people can be heroes. Also some deeper messages about personal sacrifice, the nature of humanity (i.e. just because people are capable of evil doesn't make them all evil or worth exterminating) and how love can blossom in the unlikeliest of times.
Positive Role Models & Representations
The World War I setting means there's frequent battle/war violence, as well as plenty of explosive, destructive superhero action. It's relatively bloodless, but there's a lot of it, and collateral damage can be high. The Amazons train for battle and then engage in combat (using arrows and swords) against the encroaching Germans, who are armed with guns. There's a high body count during the fights with the Germans. Diana can repel bullets with her armor; she also wields a sword, her shield, her lasso, and her wrist cuffs in battle. Several main and secondary characters die (more than usual for DC/Marvel films); some of the deaths will definitely cause sadness. A German chemist creates a poisonous gas that's released in a meeting of officials and kills them all; there are plans to release it on the Western front.
Some jokes with innuendo. Diana and Steve talk right after he's had a bath; he's naked but covers his genitals with his hands when the camera pulls away. Their conversation includes her asking him whether he's a "typical example of the male sex" (he replies "I'm above average"); she also asks what "that" is, pointing -- he (and the audience) thinks she means his penis, but she's referring to his watch. They have a funny conversation about whether he should sleep next to her (fully clothed) or not; that scene also includes references to reproductive biology and whether men are necessary for pleasure. Later, they kiss passionately after he walks her to her room; he starts to leave, then returns and shuts the door behind him, leaving it vague about whether they spent the night together. A character makes a comment about being aroused after watching Diana fight. Diana wears a tight, short, form-hugging/revealing armored costume. A supporting character lifts his kilt to warm his underwear-clad nether regions over a fire.
Language includes "hell," "damn," and "oh my God." Also insults like "bugger," "weak," "stupid," "lying," "coward."
Nothing in the movie, but part of the large, merchandise-filled DC/Wonder Woman franchise.
Ease of Play
Drinking at a pub and at receptions -- mostly beer or champagne. One character gets drunk and then gets into fights.
