Ah, the giallo. A classy Italian slasher. And no one does it better than Mr. Argento. Opera is pure Argento with a mysterious killer, trademark POV shots, and the injection of loud 80s music intense sequences. It also throws in some creative camerawork, such as the heart-beat effect and a lot of nice close-ups (loved the necklace retrieval gag and the bullet through the peep hole gag). Though not quite on the level of Suspiria or Deep Red, Opera is a great entry in the Argento canon.
