In "Opera", all gimmicky and even gruesome of Giallo topics are more than present. In absurd script saves a bit that Dario Argento has a way of making very effective and imaginative in their own way. With its narrative ups and downs, its loose interpretation (aaahhh! my dear Cristina Marsillach...) and its amazing development and resolution, the film can be seen with more pain than glory.
