I have always admired Kristen Stewart as and actress, especially when she gets a meatier role as she has in this movie.
I felt she did a wonderful job of playing Diana. She was very believable as a sweet, at times innocent and neurotic member of the royal family. So much so that before her death, I wonder if Diana ever really freed herself from her anguish?!
After watching it, it becomes even more understandable why Harry left the inner circle of his family.
