The NYT has a review from the time of the film's release that says, "puts more emphasis on bizarre special effects, which aren't at all bad." Moria gives it 4 out of 5 stars and says, "Wes Craven evinces a genuine wildness to the visions he unleashes". 1000 Misspent Hoursalso gives it 4 out of 5 stars and has a detailed plot description. HorrorNews.net has some screen shots.
Empire Online says,
Craven based the whole thing on a true story. The film stemmed from a series of articles in an LA paper about a group of Southeast Asian kids, all from the same neighbourhood, who died mysteriously in their sleep after a string of vivid nightmares. They probably weren't massacred by a stiletto-fingered sicko in a rugby shirt. But even so,Rotten Tomatoes has a critics score of 94%.
