With a plotline steeped in
psychological horror, the movie echos the styles and themes of numerous classic foreign thrillers such as the South Korean horror film
A Tale of Two Sisters, a movie which features the appearance of a similar stepmother character. The film's setting also resembled the American-Spanish
The Others (2001). Some
poltergeists and
paranormal occurrences during the climax of the movie appear to be a nod to several scenes from
M. Night Shyamalan's
The Sixth Sense. == Box office ==
