Stupidity: Bori Khan is a skilled archer and a man without honor. He's not fighting fair, and cares just to win, as established and explicitly said. He shoots an arrow at Mulan, the Witch gets in the arrow's way sacrificing herself to protect her...and for no reason whatsoever he does not shoot anymore, giving the chance for the two girls to share their very special dramatic moment together, but creating a colossal plot contrivance. It is a know movie cliche for the fight to 'pause' around the main character, but here we have a sniper who desists completely (he won't shoot anymore) for absolutely no reason. (01:29:00)
Stupidity: Diana and Steve are both characterized as heroes and highly moral individuals, but they both are perfectly fine, without giving any shadow of a second thought, with the fact that Steve is inhabiting the body of a real person, with a real job and friends, completely innocent and whose life has been taken. We don't ask for a movie to cover every possible nuance, but they make reference to his job, use his stuff, endanger the innocent body and use it 'for pleasure' too. They make a big deal of Cheetah losing her humanity, but what the heroes do is arguably worse.
Suggested correction: While this is bad writing that makes them unsympathetic, it is not objectively a mistake. They endanger the man through Steve because the entire world is at stake. They have sex using his body because they, like the writers most likely, do not consider it rape because there's no indication that the man is conscious in Steve's body or that he'll ever find out (So closer to date-rape), and ultimately, Diana wanting Steve to stay in the man's body forever, while arguably out of character, is a character flaw they both realise she needs to overcome by the end of the movie.
Not objectively a mistake? Actually I agree! Stupidity entries are in a tab separate from the proper "mistakes" tab for a reason; all those behaviors that are not full plot holes but happen against logic and character, just because they are being a tool for the plot. The movie does not make them unsympathetic by design; that would be good writing, that wouldn't be stupid, it would be human. But no, their love antics are never characterized as problematic or inherently creepy. The choices they make and that are outlined in your comment are glossed over; the movie hides the face of the guy but they both see it when they 'rape' him and when they risk his wellbeing, When she gives up on him she does it to get her powers back, she is not overcoming a character flaw, since the presence of the "other guy" is not addressed even at that moment, even if they see him. (if Steve were in a new body, the scene would have played exactly the same). Nobody could act this blasè.
Everything you've said in the stupidity entry and comment is your opinion (well, probably the opinion of the one YouTube video we've all seen where the guy bashes the film and then others repeat his opinion). Wonder Woman sees Steve, not the man whose body Steve is in. Not to mention we don't hear all their conversations about the situation because it would become clunky dialog. And before she starts losing her powers, the two really had no idea what had happened to the man. But nothing in the film regarding this situation is out of character of the "good guys" because we've never seen them in this situation (nor has anyone actually been in this situation to claim "nobody would act this blasé).
I invite you to rewatch the actual movie and not any youtube video; she sees the guy, they both do; he's never Chris Pine, who is 'canonically' never in the movie as himself. Chris Pine is what we, the audience, see. Look back at the scene of the mirror. They explain it. She says "He's great, but all I see is you." Not meaning that she LITERALLY sees Steve, but that she knows it's Steve and so she thinks of him. He even says, about himself, when he tells her to look for other men, "What about this guy" and she says "I don't want this guy." What's in the movie is out of character for any human being who is not delusional to the point of actually seeing the face of someone else. Which is what the movie needs to turn us viewers into to make the plot work.
Nothing in the film suggested to me she sees the other man after Steve comes back. I was basing my comments on watching the film (the YouTube comment was because this mistake is the same rehashed comment found there). When the camera pans around and the audience sees Steve, I took it to mean Diana sees Steve. When she says "all I see is you", I took that to mean she literally sees Steve. The mirror scene was to show the world still sees the man, but not Diana. But I can understand if others' take away was Diana sees the other man but just knows inside her heart it's Steve.
She sees that guy at the party, and only through Steve's words she then realises it's him, which the movie portrays from then on by showing Steve to us. The earlier part of the mirror scene is even more clear. He says; "Look at you. It's like not one day has passed." And she replies jokingly "I can't say the same thing about you." He does not look the same! And he in fact then goes to the mirror saying, "Right, right, right." and comments on the look of "He." So yes, I do firmly believe that it's what the movie says. If I may; the fact that some people on Youtube posted a video saying some things does not mean that anyone else supporting a specific idea - which does have a foundation in what the movie said, as I hope I clarified - did not reach the same conclusion and should be dismissed because they are lazily rehashing hersay. Glad you at least see where I come from, even if you may have not read the movie facts the same way I did.
Stupidity: So if Harley Quinn drove the truck to blow up the plant, wouldn't she have had to drive through all the cop cars at the bar murder scene? We know it was the same street because the cop gives the necklace to the detective. (00:10:58)
