Rather a jumbled plot, as the murder of a wealthy woman by her husband sets in motion a series of killings, including a couple that served as inspirations for scenes in later slasher movies. There’s no one to root for, really, in the film, directed by Mario Bava and originally titled Ecologia del delitto, and though occasionally amusing, it doesn’t quite work as a black comedy either.

  Not recommended. Otto thinks you should avoid this movie.

Movie 662 for 2021.
