Why no Wonder Woman movie?
Which is likely the biggest reason that we haven't gotten a Wonder Woman movie. -- They need me to write it. :P -- Because what people pushing for a Wonder Woman movie want is a ode to feminism... and that wouldn't be right. For all that Wonder Woman could be used to frame an exploration of gender roles and preconceptions, it doesn't work to do that flipping of perception unless the thing that Diana learns is that men are every bit as real as women are real.
Make Wonder Woman a female Captain America, as parochial and "Boy Scout-ish", as set in her ways and misconceptions and unwilling to easily get over what she knows is true... and we could have something rather amazing.
It's not going to happen... partly because the idea is pushed by people who think that Thelma and Louise portrayed "strong" women. And who think, not that a Wonder Woman movie would be awesome, but that a Wonder Woman movie ought to be viewed as a moral need.
