Shinya Tsukamoto
Twitchfilm reviewer Ard Fijn gave it a positive review saying: "Shinya Tsukamoto has made a very impressive film with some strong statements about loss and grief, and has wrapped this in a fantasy horror mystery thriller. People expecting a regular entry from one of those four genres are in for either a rude awakening or a pleasant surprise. For me "Nightmare Detective 2" was a pleasant surprise, but many people I spoke with after the viewing were less enamored by the convoluted story."
