Wonder Woman is and has been so many things, that asking what her deal is really depends upon when and where you’re talking about.
As conceived, Wonder Woman was not only a liberating figure, but a subversive one, running around in next-to-nothing, more powerful than any man, and touting ideals of empowerment and self-improvement along with her creator’s bizarre views of the importance of living in “loving submission” to a benevolent master (or mistress; Marston thought that women would eventually rule the world).
She was specifically created as a counterpart of Superman for little girls (in fact, her original name was “Suprema,” and changed shortly before her first appearance).
Beginning in the late 40’s and continuing into the 50’s and early 60’s, Wonder Woman became less and less subversive. Following the death of her creator and the implimentation of the Comics Code, her stories became more tame, she was less of a feminist, she was discouraged from showcasing her powers (and, in fact, prohibited from engaging in physical combat with a man), and spent most of her time rejecting marriage proposals from Steve Trevor (since, as a woman, marrying Steve would have meant giving up her career).
Things got sort of better in the late 60’s and 70’s, and certainly the Lynda Carter TV show boosted the character’s visibility.
In comics, the character was rebooted from scratch in 1987. Many aspects of the character were changed, making her more of a goodwill ambassador than a progressive feminist, and making her more of a warrior figure than a straight-up superhero.
That’s more or less where we are now. The big difference between early Wonder Woman and what we have today is that comics aren’t read by or targeted toward little kids anymore, and especially not little girls.
As a result, Wonder Woman’s primary function is the Justice League’s pin-up girl, and her adventures are targeted toward men between the ages of 20 - 50. She’s more violent than she has ever been, and her message is neither as focused as it was in the 40’s or as lame as it was in the 50’s. She still fights for truth and peace, but now it might involve slicing someone’s head off. Depictions of her without her boobs and ass spilling out of her costume are rare.
