You didn’t read my post carefully.She was a bit player with terrible dialogue in the first movie. They talked nothing about her history, her ancestry, and all the other components that made Storm a goddess. She was given a supporting role in the third most important story in X2. She was given the leadership of the X-men in X3 - a terrible movie which was mostly about Wolverine and Jean. Not exactly forefront.
I honestly don't know how anyone with a straight face can say the movies have done right by Storm.
Can you explain to me how she was treated the third worst without comparing her to the comics?
