Oh man, WB just can not keep it SIMPLE! I really hope Wonder Woman isn't screwed up because of this. It looks deliciously focused and intimate, with cool action... and I hope it really pulls through.
I think everyone, not just comic fans... but everyone is dying to see a cast of superhero/super villain women on the big screen. Batgirl, Huntress, Catwoman, Harley, Ivy, it's a god damn gold mine, and they really should have started with Mad Love. Harley would have been the Iron Man to their female bad-guy "avengers".
WB really do not understand what they have here. Done with care a Birds of Prey, or "Gotham City Sirens" would make a clean billion. Easily. Hell start with a Batgirl movie. That would be able to stand on it's own, especially with flashback appearances from J.K Simmons' Gordon, Batman and Robin, just more fleshed out this time. Her arc from Batgirl to Oracle. Easy money and easy Bird's of Prey setup.
It's far too early to tell, but I do hope that they at least go through with the Harley Quinn stand alone film. I figure WB will do their usual and push everything they can into it, so it will likely warp into something similar to what I said above. Buuuuuuut likely done wrong lol.
