The first Rollin film that I've really struggled to get through. The long, languorous shots where the camera slowly pans around a room from one face to another had my eyelids drooping, and the plot is as gossamer thin as Marie-Pierre Castel's ceremonial robes. I managed to make it through without falling asleep on my second attempt though, and it does have some things to recommend it.

The score by Acanthus is a real highlight - a clanging, doom-laden psych-prog freakout that jolted me back from the brink of sleep on more than one occasion. And then there's the vampire Isolde's manifestations, each weirder and more daft than the last, but still managing to keep a hint of creepiness.
