I wasn't sure I would when the movie was first announced. I didn't grow up with Wonder Woman in either live action TV or animated form. The live action was before my time, and the Justice League animated show was on cable, which my family didn't have.
I mostly thought of Wonder Woman as one of those silly superheroes running around with a flag for a costume. She wasn't the only one, but she was certainly among the most prominent. I didn't know anything about her personality or why people liked her so much other than she was the most prominent female superhero who wasn't the distaff counterpart of a preexisting male one. Though I suppose that in itself made her worthwhile.
One thing sold me on seeing the movie, and it's not what would do it for people. Because I am a World War I nut.
When I saw the first trailer with Wonder Woman stepping out into No Man's Land, I knew I had to see this movie. I love the complexity of the first world war, and how it's not a simple good guys vs. bad guys, which made it an interesting setting for a superhero movie. And there are precious few stories featuring women combatants in World War I. That it was a woman charging out there into No Man's Land meant a lot to me.
So it's a little funny now hearing from so many people that it's the best part.
I'm glad people love it, but I didn't expect that something that sold me before the movie even came out is now considered one of the best parts, because it's not something that uniquely had to be done by Wonder Woman. It's just something that spoke to me.
I've long wanted a good World War I movie (pref PG-13 because I can't take live action violence when it has a lot of gore/blood). That it turned out be a superhero movie hasn't bothered me in the slightest.
It turns out that Diana's optimism and faith in humanity works perfectly for a war with no true villain as she believes that the Germans will stop fighting if Ares is slain. Though she is not entirely correct in her initial view of human morality, she comes to understand that the morality of an individual is left to that individual. Humanity as a whole isn't monolithically good or bad.
Though Wonder Woman isn't a perfect movie, it doesn't need to be. It's one of the best superhero movies I've seen and none of the others were perfect either.
And that charge into No Man's Land is going to stick with me for a long time.
