I agree that the mall scene was very important. It completely set the tone and let you know this isn't the first movie. It wasn't just set in the 80's, it had a bit of 80's sensibilities in terms of its light-heartedness and you shouldn't look too closely at the contrivances like its magic wishing stone plot device.(or Steve being able to fly a modern jet, which was sitting there all fueled up, or just how easily they stole it, or how Diana knows how to make things invisible, etc) There was the one desperate crook who held the kid hostage, but even his buddies were yelling at him to put the kid down. This film is not going to address real evil or the truly darker impulses of humanity like in WWI where women and children were murdered. Since that was the established tone of the film, I was able to forgive a lot of stuff the script chooses to gloss over. (Steve taking over the handsome man's life was the most dubious choice, but it's still nowhere as jarring as rewatching "Back to the Future", a fun popcorn movie where - yeah, there was no doubt Biff was about to rape Lorraine)
This film sits squarely in he same world as "Shazam!" a lot more than Snyder's DCEU. And it does succeed where his Superman failed in that Diana does actually inspire people to be better. She actually does become a beacon the way Superman was never really shown to be. Take that, Bruce.
Yeah, again I did think that was the most problematic fantasy element here. (and again, this could have had serious repercussions on the man's life aside from the rape) I will say that "Quantum Leap" did struggle with the notion. Sam was himself -
his body and only looked like another person, and knew it was wrong to sleep with that person's girlfriend or wife, etc. and he said so to Al all the time. I think there was only one or two instances where he did catch feelings and did something he shouldn't have, but they always let you know it was wrong.
