This may sound blasphemous, but I'm going to say it anyway.
I'm not a fan of Wonder Woman.
That sound bad, I know. It almost feels like it's not politically correct to say you're not a fan of a venerable female character. But I'm not. From a cheesecake point of view, she may be of some interest, but after that, she's pretty dull to me.
I'm even less interested in her as a live-action character.
Lynda Carter is a tough act to follow, just from a visual point of view. She's not much of an actress, but for the time, she was perfect as Wonder Woman.
The current problem with the character is tri-fold.
First, society has become more sophisticated. We want someone who's beautiful, who's statuesque, who's in shape, who's tall, who can act. We want someone who can actually fill the depiction of the character design.
Second, society has also moved past seeing someone going around fighting in what's basically a bathing suit. At the same time, we want the character to be recognizable. That becomes a challenge in live action, because to put more clothes on her goes away from what we see in the comics, but to have her in a bathing suit will have people up in arms at her depiction.
Finally, there's the character herself. Her origin has been rebooted and retooled and rejiggered and reconfigured and just so generally muddied that it becomes difficult to say “this is her origin”. Everyone knows where Superman came from. Everyone knows Batman's origin. Wonder Woman has had several origin stories. Nailing her down becomes difficult. And really, no one cares, because her characterization is not intimately impacted by her origin. Not like Batman, Superman, or Spider-Man.
Because she's in a strange place in both origin and power set, she doesn't have a good, strong, stable roster of villains to fight. Cheetah and Giganta are there for more modern times, but these aren't what I would consider “good” characters. (Granted, I don't consider Luthor a good nemesis for Superman.) But without villains that are able to match her (or be stronger than her—because the measure of a good character is to overcome adversity), Wonder Woman won't get real traction.
I understand about Wonder Woman being an icon for feminism because one of her missions is to fight for gender equality, but there's more wrong with the character than right. Because we don't know who she is or what she is, she's always going to find it hard to find a viable entrance for today's live-action audience, despite Gal Gadot having a starring role in the next DC superhero film offering.
I hope Warners understands that whatever origin they give Wonder Woman in this film will be what the general public will know. This may cause the comics to be influenced by the film whenever DC goes through their next reboot (which is coming, never fear).
Give me a female character with a better identity, who knows herself. This will more than likely come from Marvel comics. There aren't many viable DC female characters who can lead a book, let alone a movie. C'mon, Marvel. Time to step up.
