Pathetic. A mildly misunderstood princess pities herself, narcissistically comparing her struggles with the hardships of Anne Boleyn, expecting everyone to understand her world-class misery while refusing to express herself. All this packed with the worst acting I have seen in a really long time and some pretentious cinematography which almost begs itself to be labelled "poetic cinema".
In the end, my reaction to this film lies in the poster itself: Diana puking in a toilet.
