The 'song' over the end credits.
Wholly inappropriate for a costume picture. What is the point of being historically accurate with costumes, hairstyles, choreography, etc. if you are going to ruin it with a piece of modern music, especially such a wretched choice(Sinead O'Connor???)? The director should have been told to change it. It made me cringe just like Marie Antoinette did.
Otherwise, the film was a very pretty piece of historical(semi)fiction.
