In a superhero era where characters tend to keep secrets from one another (I’m looking at you, most Arrow-verse shows) and hide their flaws from each other, Diana stands apart because she’s relatively quick to trust others with who she is and her weaknesses.
Gal Gadot has become increasingly more comfortable in the role of Diana Prince with each passing DC film.
Then, in Wonder Woman, we see her origins and the true nature of her openness with others.
As an ambassador to the world, Diana doesn’t fall into that familiar superhero cliche of withholding information or keeping people at arm’s length.
