I saw this about two years ago after searching for a copy for what seemed like forever, and I was not at all disappointed by this true gem of a movie. Director Kaneto Shindo fills the film with a superbly uncomfortable atmosphere It's a truly remarkable film. The demon mask is a freaky indeed, and the hell it causes is quite unnerving. The acting is also superb on all fronts, and the film has a sinister, foreboding mood to it that lasts throughout the entire film. This is genre filmmaking at its finest if you ask me, and if any of you have not seen this film, I suggest you seek it out as soon as possible. Believe me, this is one of the finest classics of Asian horror cinema. A masterwork of horrifying insanity. What do you all think of it?
