I think Gadot will be fine.
I'm more concerned about who they hire for the other roles. I think Chris Pine would be a good Wally West and I like the idea of Jason Momoa as Aquaman. If the Rock is Jon Stewart i'm OK with that as well.
Gadot's accent is hardly that bad. And Diana is not American, so an accent actually makes sense. I agree she will be fine.
I am worried about the rest of the League. Mamoa would be fine if they are going for the Peter David/JLU version of Aquaman. If not, I am open to suggestions, cause I am drawing a blank. The Rock for Jon Stewart is ok, Idris Elba or the guy who played Moses in Attack the Block would be my first choice. They blew the Ryan Reynolds thing, he should always have been Wally/Flash. I'm not a Pine fan.
