Wonder Woman is important.
I don't just mean that the character is an important icon to young girls who have few enough superhero role models that are regularly given visibility the way Diana Prince has (though she's still strangely under-served by modern media after 75 years), and I don't just mean that Patty Jenkins' film is important to the increasingly-struggling DC Extended Universe (though it absolutely is). Wonder Woman as an idea is important, because she embodies the concept that compassion is the greatest strength, that loyalty is greater than greed, and that love is mightier than hate.
And we need to be reminded of that every now and then. Especially now.
