“Suspiria” (*1/2 out of four) was a pointless and unpleasant remake of Dario Argento’s classic 1977 original about a maddening darkness that lurks at the center of a world-renowned dance company which engulfs and endangers an idealistic young dancer (Dakota Johnson), the mean-spirited artistic director (Tilda Swinton), and a grieving psychotherapist (also Swinton) and they soon all find themselves struggling for their sanity and survival. Alternately disgusting and boring and it never reaches the hypnotic artistry or dazzle of Argento’s original. And it goes on forever at nearly two-and-a-half hours (nearly an hour longer than the original)! Jessica Harper from the original has a minor cameo here but that comes at the very end and is hardly worth sticking around for.
