well, I'm afraid that they'll take it and make it something horrible and lipstick girl-power, like Catwoman ("Think Spiderman- but with cats instead of spiders!") or Electra ("Think Spiderman- only with electras instead of spiders!"), but I was actually relieved when Whedon got tapped to do it.
Of course, there were two guys who wrote a WWII-era script for it, which they bought (I think they didn't like Whedon's take on it, or something like that, and were looking for ideas to throw at him), but now that Whedon is gone, I'm a little afraid it's going to suck again.
