So chick buys vase, vase is possessed, chick has sex with vase inhabitant (her name is Suk btw) and boyfriend (his name if Fuk) finds out. Either way they both die (both Suk and Fuk that is) and the vase is broken. So something or a rather and the dead boyfriend ends up getting cursed to remain a ghost and reeking havok on the living. Oh, but before that back when the boyfriend breaks the vase there is an hilarious body horror scene worth checking out for gore fans. You don't want to skip that.
So anyhow now we have a dead Fuk who starts off possessing animals then a human who becomes like a super nasty possessed being that is near unstoppable. I mean this bad boy can literally teleport himself around anywhere where-ever he wants and almost kill anyone he wants to anyway he wants, talk about unfair advantage. He's got telekinesis, can divide himself, become ethereal, stretchy body, flying, lasers and much much more. Btw, the priest fight was excellent, that happens around the 64 minute mark.
It's a pity it takes an hour of viewing until things ramp up. There isn't a great deal of intelligent dialog either. The music was good to awesome which made up for a lot of the poor acting and sound effects. The special fx are inline with most Asian horror's of its time or maybe a fraction better. Just a pity there was so much boring stuff to get through before it really took off. All of this said I absolutely freaking loved the ending especially the music that went with it. Wow, nice!
