Like a cross between Zulwaski's "Possession" and "The Entity", but don't take that to be an endorsement-this lame duck of a movie doesn't posses any of the intensity of those two movies (and certainly nowhere near as disturbing as the Zulwaski film). Anyone expecting something on par with "A Tale of Two Sisters" or "I Saw the Devil" will be severely disappointed.
The film follows Yeon-sul, a young college bound woman whose psychotic former lover has returned to carry on their relationship, and who stalks her as she continues to refuse him. However, she's also raped by an incubus, a ghost that wants sex with women.
If you're wondering what these plot lines have to do with each other, well, nothing, really. Of course not everything in a movie has to tie in directly, but in this case all that's happening is that the stories are competing for screen time and attention, like two people fighting over the last window seat on the bus. Worse than that, neither are particularly terrifying or even interesting. The stalker is barely threatening, and nothing but cheap, stereotypical techniques are used to try and make him intimidating, which wouldn't be a problem if they were done even remotely effectively. The incubus scenes are laughable, coming off like soft core scenes, relying on the actress to try and convey the horror being brought upon her after the fact. The problem being, the actress isn't very good.
There's no real build up to anything. The plot gets going right away. The characters are paper thin. Even the stereotypical characterizations in a slasher film can at least be fun to watch until the inevitable slayings. These characters are not only paper thin, but dull as dirt, and we're spending most of the film with them bumbling around waiting for either the incubus or the stalker to underwhelm us with their presence again.
Not even worth watching just to kill eighty minutes, there's thousands of better movies that could do that. Taking an eighty minute walk around in broad day light in a friendly, low crime neighborhood will produce more terror and anxiety than this piece of cinematic dead weight.
Are there any positives? Well, it's competently made, that's about it. I'm not making the argument this is one of the worst movies you'll ever see, not by a long shot, but it is excessively difficult for me to name any legitimate redeeming values.
