I consider this film a Giallo which generally means a thriller and specifically an Italian thriller but has come to mean any thriller with high production values where the perp is hidden. I.E. Hitchcock or Dario Argento. This is not a "horror" movie. It is a great character study with beautiful cinematography, a nice story line that gets you invested in the characters and a wonderful atmosphere. I am generally a horror fan but I like Giallos and enjoyed this very much. I would say if you enjoyed movies like Suspiria or Rear Window, you will probably enjoy this. I do not compare this movie to those, but it may give you an idea of the type of movie it is. I was very impressed by the overall quality. That's pretty much why I am writing this review. I watch a lot of movies and a lot are sub par. This movie deserves more attention. No, I am not in any way related to anything to do with the production of this movie. I am just a fan of quality movies and a critic of horrible movies. Call me silly but I think that is what the reviews on IMDb are supposed to be about.
