Gaines was troubled. Roubicek, who worked on Superman, too, had invented kryptonite. She believed superheroes ought to have vulnerabilities. She told Gaines she thought Wonder Woman ought to be more like Superman and, just as Superman couldn’t go back to the planet Krypton, Wonder Woman ought not to be able to go back to Paradise Island, where the kinkiest stuff tended to happen. Gaines then sent Roubicek to Bellevue Hospital to interview Bender. In a memo to Gaines, Roubicek reported that Bender “does not believe that Wonder Woman tends to masochism or sadism.” She also liked the way Marston was playing with feminism, Roubicek reported: “She believes that Dr. Marston is handling very cleverly this whole ‘experiment’ as she calls it. She feels that perhaps he is bringing to the public the real issue at stake in the world (and one which she feels may possibly be a direct cause of the present conflict) and that is that the difference between the sexes is not a sex problem, nor a struggle for superiority, but rather a problem of the relation of one sex to the other.” Roubicek summed up: “Dr. Bender believes that this strip should be left alone.”
Critics such as Valerie Estelle Frankel support Jenkins's vision. Frankel argues that the film subverts the male gaze, stating that the construction of Wonder Woman tends to shift every few decades as it reflects the state of feminism during different time periods, including third-wave feminism (which reflects Jenkins's approach). Zoe Williams offers a similar argument, stating that while Wonder Woman "is sort of naked a lot of the time," that is not, at the same time, "objectification so much as a cultural reset: having thighs, actual thighs you can kick things with, not thighs that look like arms, is a feminist act". Williams then juxtaposes Wonder Woman to past female action heroes such as Sarah Connor, Ellen Ripley, and Lara Croft, whom she suggests were all constructed for the male gaze, in which a "female warrior becomes a sex object", (a point which she argues that Jenkins directly references in the film).
In May 2017, early tracking had Wonder Woman opening with $65–75 million, and possibly as high as $105 million. The film opened Friday, June 2, 2017, across 4,165 theaters and made $38.7 million on its opening day, including $3.7 million in IMAX. It was the biggest single-day gross for a woman-directed film, ahead of the $35.9 million opening Friday of Catherine Hardwicke's Twilight in 2008 and the biggest opening day for a woman-led comic book superhero film, ahead of Ghost in the Shell ($7 million). This included $11 million it made from Thursday previews, also the best start for a film directed by a woman, surpassing Fifty Shades of Grey's $8.6 million which was directed by Sam Taylor-Johnson, and the third-biggest of the year, behind Beauty and the Beast and Guardians of the Galaxy Vol. 2. Of that, $1.5 million came from IMAX screenings.
