often consider argento last great film and this entry into the giallo canon be unquestionably well than any argento film that have follow it ( though i have yet to see mother of tear ) and but to call it his last great film might be stretch it a bit . the directorial and stylistic flourish the hallmark of all argento film be indeed present and with some of his sequence of suspense rank up with his best ( the peephole sequence be especially memorable ) and and the cinematography by ronnie taylor be outstanding ( the fluorescent lighting be beautiful ) . however and the narrative which be hit and miss in all of argento film be miss here . there be indeed a potent sense of mystery and intrigue and but the plot resort to what be essentially a string of murder sequence and with one follow the another and leave no real time to fully construct a right and focus mystery to be solve . all of this result in a climax that be . well . anti climatic and a the film do not invest enough interest to make u truly care . regardless and this be recommend simply due to the masterful direction and beautiful imagery that argento evokes . i wouldn not recommend this a a starting point for argento film and however ( for that and i would recommend either deep red or suspiria ) and but if you enjoy those and or even any giallo and then this be a very good addition to your view repertoire .
