"Nonviolence, however, doesn't break box-office records."

Exactly. Show me a nonviolent superhero and I'll show you an empty movie theater. Then again, superheroes of the DC/Marvel type don't exist anyway, so I wouldn't sweat their inadequacies as role models. If you want moral exemplars, read the Lives of the Saints. If you want to be entertained while munching popcorn, go see a superhero flick.

What I found most affecting in 'Wonder Woman' was the protagonist's journey from dewy-eyed innocence to a sadder-but-wiser understanding of the human condition. In a way, Diana acquires the age of reason during the course of this movie. At the end she knows the truth, so she is now accountable for it -- as, ultimately, are we all. 

If I were still in youth ministry, that's the catechetical nugget I would mine from this film.
