What a great post. This will be the most important pop culture movie of its time.I actually agree with you on that. The burdensome part always stemmed from the perception that Wonder Woman is the one icon WB/DC absolutely cannot screw up. Crappy Batman and Superman movies? We can deal with that. We can laugh at GL's yellow turd monster and Bat-nipples and Superman snapping mofo's necks and feeling up Lois Lane in the aftermath, even if that laughter is only to drown out our silent fanboy sobs.
But messing up Woman Woman on the big screen? Ho Ly Sheet. A bad Wonder Woman movie, in this Tumblr day and age, will end all things. Tectonic plates will shift. Birds will fall from the sky. Fetuses will commit suicide in a display of pre-birth feminist angst.
At least that's how the meat-factory execs see it. I'm sure the truth is a lot more tame, but among the DC pantheon Wonder Woman is the only superficial representative of The Other (well, since J'onn's been demoted and John Stewart isn't the default GL in the majority's eyes). WB did itself a favor with the hiring of Rock, Mamoa, and by elevating Cyborg to elite status, but Diana is still the only member of the Holy Trinity that's not the "default". She's not only a woman, but she's exotic, and she was raised by what's possibly a society of multicultural gender-queer butt-kicking warrior chicks who worship non-Christian/Muslim/Judaic gods. A lot of groups have a lot of personal feeling riding on her success.
Yes, WB should've been confident enough to make a WW movie by now. This should've been done a decade ago. But I get the hesitation, even if I don't agree with it.
