It is not educational because it is not true! This is not Harriet's version of her story, this is Hollywood's version and they glossed it up, changed it , lied and then lied some more. It's really a shame because now that it is out we All need to go get the book by Sarah Bradford that was dictated to her by Harriet Tubman.
We can not allow Hollywood to educate our children because they will never tell the truth. Over half of the main points in the movie was lies, there were no black snitches mentioned in her book, so where did they come from? Lies. Hollywood made them up.
