Princess Diana commands respect both as Wonder Woman and Diana Prince; her epithetical title – The Amazon Princess – illustrates the dichotomy of her character. She is a powerful, strong-willed character who does not back down from a fight or a challenge. Yet, she is a diplomat who strongly "favors the pen", and a lover of peace who would never seek to fight or escalate a conflict. She's simultaneously both the most fierce and most nurturing member of the Justice League; and her political connections as a United Nations Honorary Ambassador and the ambassador of a warrior nation makes her an invaluable addition to the team. With her powerful abilities, centuries of training and experience at handling threats that range from petty crime to threats that are of a magical or supernatural nature, Diana is capable of competing with nearly any hero or villain.
A. O. Scott of The New York Times wrote that it "briskly shakes off blockbuster branding imperatives and allows itself to be something relatively rare in the modern superhero cosmos. It feels less like yet another installment in an endless sequence of apocalyptic merchandising opportunities than like ... what's the word I'm looking for? A movie. A pretty good one, too." Michael Phillips of Chicago Tribune compared the film to Captain America: The First Avenger, noting that as with "the first Captain America movie over in the Marvel Comics universe, DC's Wonder Woman offers the pleasures of period re-creation for a popular audience. Jenkins and her design team make 1918-era London; war-torn Belgium; the Ottoman Empire; and other locales look freshly realized, with a strong point of view. There are scenes here of dispossessed war refugees, witnessed by an astonished and heartbroken Diana, that carry unusual gravity for a comic book adaptation." Katie Erbland of IndieWire commended its thematic depth, explaining that "Wonder Woman is a war movie. Patty Jenkins' first—and we hope not last—entry into the DC Expanded Universe is primarily set during World War I, but while the feature doesn't balk at war-time violence, it's the internal battles of its compelling heroine that are most vital." Alonso Duralde of TheWrap similarly felt that, "Diana's scenes of action are thrilling precisely because they're meant to stop war, not to foment it; the idea of a demi-god using love to fight war might sound goofy in the abstract, but Jenkins makes the concept work." Ann Hornaday of The Washington Post praised Gadot and Pine's performances as well the film's detailed plot and narrative while comparing of some slow-motion action sequences to The Matrix. Stephanie Zacharek of Time magazine hailed the film as a "cut above nearly all the superhero movies that have been trotted out over the past few summers" while praising Gadot's performance as "charming" and "marvelous" and commending Jenkins's direction of the film as a step forward for women directors in directing big-budget blockbuster films in Hollywood.
Wonder Woman did not keep her identity a secret, and initially did not consider herself a superheroine. Indeed, her character was wide-eyed and naive, innocent and without guile. Diana spoke only Themyscirian, a variation of ancient Greek, and had to learn English when she arrived in the United States. Fortunately, Diana soon met Julia Kapatelis, a scholar in Greek culture, and her daughter Vanessa Kapatelis who helped the Amazon princess adjust to the world of men. However, for all her apparent naiveté, Diana was a trained warrior, and had no compunction against using deadly force when called for. For example, she felled the god Deimos in battle and felt completely justified under the circumstances. Through Pérez's tenure on the book, Diana confronted war, injustice, inequality, death and conflicts involving the Olympian Gods.
As the men helped the Amazons prepare for battle against the First Born's army, Diana received news that the First Born had been attacking other gods' realms. With Eros and Artemis, Wonder Woman ambushed the Minotaur at Demeter's home. Unfortunately, the First Born had already defeated Demeter, so Wonder Woman sent her companions to safety while she confronted him by herself.
