Diana's original origin story was my least favorite part of the character. She was made from clay, had an invisible jet that didn't make her invisible as well, and she would lose her powers if chained or handcuffed. Each change/tweak to her origin and power set has been a boon. Giving her flight and eliminating the silly plane, and doing away with bondage as her weakness were great changes. And I like how the movie handled the clay origin to hide her true parentage. It adds another twist and more possibilities for future plot lines. The core of her character isn't changed. She was still nurtured and trained by the Amazons as a daughter, and niece. It is her growing up among the Amazons, and her ideals that truly define her character.
