Widely regarded by Dario Argento fans as the horrormeister’s masterpiece, Suspiria is an impressively accomplished chiller that just wants to put you on edge for 95 minutes. The flimsy plot concerns a young American woman who discovers that the German ballet school she has joined is a cover for a coven of witches. But you can forget that. Argento does. His interests lie in menacing us and his heroine with tumultuous weather conditions, his camera, a loud and scary soundtrack by Goblin, and the threat of sudden acts of explicit violence. And he succeeds brilliantly.
