I love it especially the iconic eye-face effect but the lead actress really steals the show and the cinematography is outstanding too with some great use of shadow (and color of course). Having watched a fair amount of giallo now, this one certainly stands out with the killer's unique bizarre visions of his victims. There are some nice twists and turns too that keep you guessing about the murderer's identity. I'm so happy my friend Jason recommended this to me. Thank you! This is absolutely an awesome film and I just had to get the rare Code Red Blu-ray with the perfect cover. If you're curious to see more Italian horror, this and Torso are my favorites besides Argento's classics of course. Fulci's Don't Torture a Duckling is up there too. It's really an amazing time to be a movie lover. I just hope people keep supporting physical media because so often rarer titles are not on streaming sites (neither are all the awesome extras and I just love behind the scenes docs).
