If I were to reboot Wonder Woman on the big screen
I would look to Geoff Johns recent attempts to tie Wonder Woman to the justice society and make a movie about their adventures during the Second World War
Rebooting both franchises in one fell swoop
You can even make a whole JSA trilogy centered on Diana’s adventures ending with the end of the Second World War and the death of Steve Trevor
Causing her to abandon man’s world
And leading into her modern day adventures with Barbara Anne Minerva whose a new love interest to Diana
Whose relationship for one reason or another falls apart, leading to Barbara becoming cheetah
Which causes her to feel lonelier than ever till she meets the justice league and creates a wonder family
This literally Writes itself
