Stupidity: Given Max's powers, it's curious why he doesn't touch the soldier driving next to him and convince him to wish away Wonder Woman, or for her to stop or be injured.
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: Max is shown fulfilling the various wishes that people express to him, and never turn down any; it would not fit what he became anyway, which is a wishing stone. If people touch him, he has to comply. The wishes he can grant have seemingly no limit, and yet, in this predicament it takes a humongous level of suspension of disbelief to assume that in a climate of global war and chaos, NOBODY wishes for things to go better in any way and the nuclear war to be stopped. There are even in some street scenes "Ban nukes" signs; surely some of those guys must have wished for the madness to stop.
Suggested correction: The Dreamstone was also created by the Duke of Deception to bring chaos into the world. It brought out people's selfish desires. When Max Lord became the Dreamstone, he was able to continue to manipulate people in wishing what they truly desired, wishing for more than than had. In the comics, Max Lord had the ability to telepathically alter people's minds after he became a metahuman, so it seems the film incorporated this power as well. It/He made people wish for selfish things. That was the purpose of Wonder Woman's monologue, to tell the people to become less selfish, so give up their wants, to be the hero to save the world by giving up their wish (and wish for a better world would have cost too much, so that wouldn't be an option).
"Cost too much" is not a rule established in the movie, since desires like the deportation of the Irish, "Wish I never met you" "want all the money in the world" someone says in background have astonishingly powerful ramifications. LIkewise why would it be an implication that he is the one who makes them wish only selfish things? The movie wants to say that there are no 'good' wishes when you take shortcuts to make them happen (or at least it tries to referencing the Monkey paw) but to do so shows only wishes that are rotten to begin with.
Suggested correction: With so many people wishing at the same time, it's logical a lot of people are wishing for the opposite. I'm sure the stone's power has some way of dealing with conflicting wishes. For example, someone could wish for the world to blow up or burn, whilst others wish that everybody will be happy and healthy. So, nothing much happens that threatens human existence (the stone would be worthless if all humans are dead) as those wishes cancel eachother out. But the nuclear war happened before Max started talking to everybody, so that is happily continuing.
Most people would have wished the nukes to disappear pretty instantly especially with the world falling into chaos and everyone panicking about it.
And others would have wished for them to hit and kill the "heathens" or "hateful." Cancellation.
