Great and very unique Vampire film. Not graphic or explicit but from the school that focuses on presenting theme and original rendering of an old classic allegory. Very original. Recommended for those who are familiar with classic Vampire characters (like Isabella, the lead here). This is indeed a horror story, its themes that may take some effort, literacy, or familiarity with the Vampire subgenre, but the very final scene will confirm this fact for those who watch it to the end. It comes from an era of film, on the latter timescale for its genre, where a few Vampire films, like Martin (1977, Romero) for more famous example, strove to be more original, contemporary and imbued with larger scope of meaning and themes, in addition to weaving in story.
The settings: a small Polish city, forests, castle and beach. One Vampiress and her bats. One castle sanitorium and a clinical doctor who buys Izabel's batwinged tea cups one day...
I would go so far to say this is both a slower burn at first but brilliant, it shines in the conclusion where all is revealed.
