I usually defer to Grace Randolph's insider knowledge about situations like this, and I agree that this isn't exactly over yet. If the WB and Cavill (and his "manager") can get over this game of chicken, they might still work something out. Personally, I think he made a great Superman/Clark Kent & given the right material he could really shine in this role. A good director with a hopeful vision could also make a difference.
If not, then I don't see any reason why Wonder Woman couldn't carry on as this franchises centerpiece as they scrap what came before and enter their "Phase 2".
I agree with all of this.
It's not about 'deserve' it's about what you believe. And I believe in Love.
