WW should be at the forefront in term of this cinematic universe goes
Gal Gadot was piff and stole the show in BvS and the way she fights I feel will tie in nicely with her Amazonian world, plus shes a decent actor
An Amazonian world I think Snyder could handle and give it a more cinemtic/dramatic edge kinda like that Apocalypto feeling
No one likes Aquaman and hes not necessarily the most marketable character, theyre better off just throwing him in the Justice League movie and give him an impromptu introduction and later on show a bit more of his back story and world as the movies go on kinda like how Marvel did with Hawkeye which worked out well
