Arabella, l'Angela Nero on AllMovie

A favorite of bad-movie buffs, this ludicrous thriller concerns a nymphomaniac (Tini Cansino) who visits sleazy sadomasochistic sex clubs at night. Cansino's foul-tempered husband (Francesco Casale) is supposedly paralyzed following a traumatic oral-sex-related car accident, which also resulted in his emasculation. The scissor-wielding killer could be Cansino, Casale, a lesbian detective whose mother once castrated her father, or Casale's mother (Ida Galli), who drives through areas frequented by male prostitutes muttering "Hell is Heaven." The revelation that Casale was only faking his paralysis to cure writer's block is just one highlight of a film filled with characters who defy nearly every known rule of human behavior for no apparent reason.
