When a director distances himself from a movie that is never a good sign. And after watching this movie I have to say that he is right to do so if there is truth to this claim. There was a time Dario Argento could do no wrong. So what exactly happened? Maybe we will never find out. But for now I understand very much that this isn't a movie to be proud of. There is not one scene that shows the master's brilliance. It does make me wonder what the movie could have been without the interference of the producers. It also doesn't help that the story is quite weak. There are no twists and turns. Well, maybe a very little one. None concerning the Killer. But the biggest flaw of "Giallo" is the lack of real tension and suspense. Even when the killer is known a giallo movie should provide thrills. Otherwise what would be the point of this movie. (Thinking about it, this movie can be seen as a bad parody about the giallo genre.) Adrian Brody and the beautiful women are the only things that stand out in this below average product. Avoid big time!
