Perhaps one of the top mystery-thrillers of the 1980s; if you like films like "The 4th Man" (1983) or "Body Double" (1984), you'll fancy this one too. Well-constructed twisty-turny plot, virtuoso camerawork, sudden shocks, terrific synthesizer score, supremely good-looking female cast. It's also surprisingly self-reflexive: the character of the writer can be seen as a stand-in for Argento himself, who uses him as a means of addressing some of the most common criticisms made against his films. This is peak Argento. *** out of 4.
