I watched this with a few people and it was really fun to laugh along at the ridiculous plot developments. It starts off way too serious and strange... there is a spousal abuse scene that is difficult to watch. That happens in an... orgy party I guess... scene, and the movie has frequent nudity and sexuality. The Poe story seems to only influence the movie a little, but knowing the Poe story does certainly spoil the very ending. Regardless, the most enjoyable part of this was laughing my friends at how crazy the plot and characters became. The ending is typical for Giallo, and overall this movie isn't terrible and isn't great. Some fun and good moments are here, adding up to pretty middle-of-the-road fare.
