Kristin Stewart could certainly not be accused of being half-hearted here. She immerses herself completely in this depiction of a rather unstable woman dealing with the pressures of her fame and her family. The extent of any authenticity as to the feelings and experiences by the real life Princess is anyone's guess, so though I did appreciate her effort, I felt the rest of the film took a rather uncompromising view on other people who are either dead, or unable to retaliate against this somewhat one-sided portrayal of a scenario that all concerned have subsequently admitted was way more nuanced... llegiu la resta.
