What's Your Dream Superheroine Movie?

So, the huge success of Sex and the City has made me optimistic about female comic book superhero movies, perhaps foolishly, given the terrible, terrible treatment given most female superheroines by Hollywood so far...do I need to mention names? Aeon Flux, Catwoman, Underworld, etc...Bad writing, bad budgets, it's like they were trying to sabotage these movies or something!
But the success must mean that girls are desperate to see movies about...gasp...girls! You know, with stars who are female. And stories that are interesting to females.
So, besides the Joss Whedon Wonder Woman movie, what would your dream superheroine movie be? Who would you cast? Who would write it?
