Just saw "Dr. Strange", which was only redeemed by Mr. Cumberbatch and some humor. I think it counts as maybe the only superhero movie we've seen. Got to thinking: back in the day our heroes were in Westerns. They stood out because of courage and usually moral status and being fast on the draw. Children, boys at least, could aspire to that status.
I don't know what lessons or models our modern superheroes present for children.
(My, I sound like an old fogey.)
