Basically, the film is about a haunted house. There are several story threads that each take place at a different time over a period of several years. Anyone who enters the house is affected by a curse - they are haunted by the ghosts of a woman and a young boy. Not only do the victims of the curse suffer an unnatural fate, but the curse can actually infect people they come in contact with!
There is a romance subplot as he falls for a young waitress. There are some great fights, and a twisted ending.
Once out of the clinic, the vampire priest must combine his religious morality with his new-found bloodlust and heightened physical sensations. He befriends the lonely wife of a cancer patient, and starts an adulterous affair with her. This is the core of the story, with the vampirism merely as part of the backdrop. It is taken from a book by the French novelist Emil Zola, and is apparently the only version of the story to feature any vampires. Much like Pride and Prejudice and Zombies , this is a mainstream story with genre aspects added.
The problem seems to be the beginning of the film, which is slow-moving and concentrates on introducing the protagonist before he becomes a vampire. But since the story is about the affair, not the vampirism, this is not really relevant.
The title character is a vampire who looks like a young woman. At night she prowls the streets of Bad City, an oil town in Iran. With her wearing of the traditional female headdress, and her targeting of hedonists like junkies and alkies, she seems more like an Islamic traditionalist than a feminist icon. This has more in common with medieval morality plays than with modern, intellectually-challenging films.
Strangely for an American movie, the monsters are oriental dragons and the caucasian characters are reincarnations of Korean heroes. In fact this was produced in South Korea, which accounts not only for the Asian look to the production design but also for the high quality of the CGI SPFX, especially when one considers that the film was made on a modest budget several years ago.
The Evil Overlord's forces, looking like the Gungan Army in Star Wars: Phantom Menace , march into the centre of Los Angeles and take on the US Army's M1 Abrams main battle tanks.
