Pretty good actually. Good directorial skill, nice setting. The suspense built slow, some viewer might not like it. The title itself could be exploited as a main theme, but it doesnt seem so. The twist at the end, even though turning back from the title, is totally unexpected, I believe only a few would have a thought of it.
This is exactly what to expect from the director of "St-Maud". A history of love and violence with a lot of "noir" and "fantasy". Excellent acting and great score by Clint Mansell.
