1. Wonder Woman is unrelatable
An immigrant who basically feels that their whole life, they have been sheltered, and must now face an evil that they are unsure if they are ready for, is unrelatable?
2. Wonder Woman is too powerful
Fanboys: Lol look at how strong Hulk is Avengers. Isn't it cool how no one can stop him? Isn't it funny how how easily overpowers Thor and Loki, who are being terribly written and we're accepting because it's teh gaud ov geak JOsS WhEdOn?
3. She has no good stories
Take Gods and Mortals, update the U.S.S.R. to the Middle East, China, or North Korea, make Steve the love interest, and you literally have a movie written for you. I have NO clue how this has escaped the psyches of so-called "professional" screenwriters.
4. She has no good villains
Ares is literally the embodiment of War, and at the end of Gods and Mortals, she realizes that even with her training and powers, Ares is FAAAAAAR too powerful for her to take down. As opposed to, oh I don't know, that lame movie version of Loki who is sad that he is a tragic mulatto and could probably get beaten up by Happy Hogan because he is so weak and useless.
5. She is tied to WW2.
No she isn't. I guess Superman is tied to the Great Depression and the Hulk is tied to 50s monster movies. Yeah, you need new material. FAST.
6. She is perfect
A young, naive, fish out of water, and you're telling me that there is no writing potential? While you get new material, you should probably check into a creative writing class at a local college. You need it.
