As a longtime fan of Suspiria, and of Argento in general (at least up until Opera), I had some enthusiasm for this title. Okay, I didn't expect it to be as great as the movie which kick-started the Three Mothers trilogy, especially since this final installment comes nearly three decades later, but I still had hopes.
The best I can say is that I didn't entirely hate it.
Nearly every scene is stolen - well, self-cannibalized, to be fair - from previous works by the director, and those which aren't are either overly garish or strangely lackluster. The acting was uniformly awful, which isn't unexpected, but damned if it wasn't worse than usual. The score is decent, but a far cry from the maddening strains of Suspiria. The dreamlike qualities of particularily Suspiria and Phenomena, which covered many of those films flaws, are not present here.
Unless you're an Argento completist who absolutely NEEDS to know, it may be in your best interests to rent this title rather than buy it.
