It was so bad that it made me realize I could be a screenwriter.
I think what happens is Zach Snyder gets together some good ideas for characters and stories (and some pretty mockup pictures), then he uses those to sell the project. Unfortunately from there, he doesn't or isn't able to flush those ideas into a compelling narrative with engaging characters. Everything stays very 1 dimensional.
I suggest a hard pass to everyone.
Do you mean Hellen Keller? Anne Frank was the girl living in the attic during nazi occupation in World War II. Helen Keller was blind and deaf and, to my recollection, wasn't able to communicate until adulthood when a teacher came along to teacher sign language.
