I have so many conflicting emotions over this announcement...
On the one hand, there's the part of me that's waited DECADES to see Diana on the big screen that's jumping up and down, dancing a jig, and screaming "HOLY FRAK, WE'RE GETTING A WONDER WOMAN MOVIE!"
On the other hand, there's the part of me that realizes that DC doesn't have the slightest idea what to actually DO with WW, as evinced by their decision to throw out the classic backstory that made her different and unique (and emphasized the relationship of mother and daughter) in favor of the "she's one of Zeus's billion-and-one bastards" New 52 background.
The long and short of it is that I hope this actually gets Marvel off their asses so they'll actually put out a Ms Marvel or She-Hulk movie... and in the end, it's going to take something truly heinous to keep me away because HOLY FRAK, WE'RE GETTING A WONDER WOMAN MOVIE!!!
