A remake
After watching the two supposedly sequels for "Rosemary's Baby" ("Look what happened..." and "The Son o Rosemary"), it's staggering to me to realize how this movie have more similarities to Polanski's masterpiece than the others.
Of course, everything today is inspired by something already made, but this one goes too far and it just make it worse. Its looks like a terrible, pretentious and amateur remake with gaps filled by paper-cuts of The Ring, The Skeleton Key (or The Innocents), Dark Water, and many of recent thai/japanese horror movies aesthetics.
There are horror movies, trash movies, and for this one, should be a special genre; frankenstein b-movie.
