Entertainment Weekly interviews Joss Whedon, and he has some things to say about the Wonder Woman movie:
Everything that was hard at the beginning is still hard. I don't feel like I've nailed it yet, and I think the studio agrees. So I'm still plugging away. It's probably not as hard as I think it is, because I'm still a little fired from my TV decade. I should have taken a year off. It's now too late to realize that. But it's a big job. And besides her great origin story, there's nothing from the comics that felt right 100 percent, no iconic canon story that must be told. Batman has it made — he's got the greatest rogues gallery ever, he's got Gotham City. The Bat writes himself. With Wonder Woman, you're writing from whole cloth, but trying to make to feel like you didn't. To make to feel like it's existed for 60 years, even though you're making it up as you go along. But who she, and what the movie, is about, thematically, has never been a problem for me. But the steps along the way, it could be so easy for them to feel wrong. I won't settle. She wouldn't let me settle.
You go, Joss! Give Wonder Woman the respect and movie she deserves! Yay!
