Cara's performance as Enchantress has been a bit controversial based on test screenings. I've only seen one person say she was good.
Here are the others who were up for that role.
Brie Larson
Saoirse Ronan
Blake Lively
Alicia Vikander
Emilia Clarke (Game of Thrones)
Shailene Woodley
Megan Fox
Ellen Page
Alexandra Daddario
Emma Stone
Kyrsten Ritter

Lets hope the the General Audience likes Cara/Enchantress better when the movie drops. Maybe cut around her a bit?
Also who would you like to see those actresses play in the DCEU? All except for Brie Larson should be available. I think they'll try to contact a few of them for the Birds of Prey movie and SS 2.
