but when your main villain is the Cheetah (she's a woman dressed as a cheetah - oookay)
That version of the Cheetah hasn't been used in 25+ years. The modern Cheetah (Dr. Barbara Minerva) is a werecat-type; far more dangerous (when she's not being written by Will Pfeiffer in
Catwoman).
Wonder Woman wasn't really interesting to me until Xena premiered and captured my attention; then I realized that the post-Crisis Wonder Woman and Xena were very similar characters (something DC has only emphasized after Xena came on the scene).
No, she isn't. At all. The characters are nothing alike. Xena is a barbarian warrior like Conan; Diana is a noble diplomat and peacemaker. People comparing to Xena has done the character immense damage.
I find her Warrior/Peace Bearer stance a contradictory and clumsy mix.
This is another thing that has been completely misread about the character ever since
Kingdom Come's hamfisted take. There is nothing whatsoever contradictory about that, any more than a cop or a UN peacekeeper carrying a gun. Creating a peaceful world means dealing with warmongers.
Now, as to the comics, the character has suffered from a lack of consistency. DC editorial has repeatedly allowed subsequent creative teams to dismantle the work of the most successful runs; Perez was followed by Messner-Loebs, who, though he did contribute some interesting/valuable stuff (Artemis, the Donna Milton story with Circe), got rid of most of Perez's supporting cast and situation; Jiminez and Rucka's runs were followed by the nostalgia-vomit-cocktail of Heinberg and then
Amazons Attack. DC's current "let's skip back to the Silver Age" creative trend is frequently detrimental, but nowhere moreso than here, because Silver Age Wondy
sucked. Of course, the people in question aren't really thinking of the actual comics, but the...
...Lynda Carter TV show, the other big burden on the mythos. Because it also really, really sucked. But it's got huge nostalgia vibes from the current generation of creators. Whatever it's merits at the time (and there were precious few of those), it's no more a guide to the character than the Adam West Batman.
Diana right now is basically where Batman was in 1988; she's still waiting for Tim Burton to present a serious, dramatic take to the public in lieu of the campy memories of yesteryear (there are a lot of problems with Burton's Batman, but it efficiently showed people that Batman was allowed "ZAP! POW!").
The only media she's gotten since has been in the more limited realm of animation from Bruce Timm, a man who couldn't write a proper Wonder Woman to save his goddamn life; it's depressing, really, given his talent, that all he's got is a knockoff Xena in JLU, and a slightly modified version in the animated film. All the great writers starting with Perez try to move beyond gender-war, and all the bad ones get hung up on that, and Timm is one of them.
