By far the worst Argento film I've seen. The story is plain stupid, although the story has never been the most significant part of the Argento parcel. This time his visions have lost it's edge totally, the splatter and gratuitous typical Argento-violence is there, but that and his infatuation with opera is the only thing reminding of his previous work. Acting isn't much, but you still see the occasional wonderful camera moves and he has always used music very convincingly. As a whole it is disturbingly lame production from such a grandmaster, whose previous Stendahl's Syndrome was just mindbogglingly powerful masterpiece. Hope his next giallo film has same grit his former giallo visions have portrayed...
