These distinct "thematic and stylistic tropes" constitute a loose definition of the genre which is broadly consistent, though various critics have proposed slightly differing characteristic details (which consequently creates some confusion over which films can be considered gialli) [REF].
The typical giallo protagonist is an outsider of some type, often a traveler or tourist, and usually a young woman (gialli rarely feature law enforcement officers as chief protagonists, which would be more characteristic of the poliziotteschi genre) [REF].
