As triumphant a movie as all his other three animal movies Dario Argento hit a home run with his artsy murder mysteries. And I must press that Argento really has made murder and death into art – I believe no one ever has made such telling and beautifully terrible death scenes as the master. Add to that the relatively good dialogues, acting plus some very odd humour (focused on a select bunch of weirdo characters populating this thriller) and this is movie that is a must see for any horror fans. Two killings are of extreme note – the first murder in the garden and than the final death scene.

Naturally as always not all is well with the Argento movie. Some of the acting is off and the plot/script has a lot of holes with much room for improvement. Also character building is almost non-existent as Argento typically for him focuses on the atmosphere (to great effect). The camera is as always stylish plus we have some great score from Enrio Morricone to really punctuate the whole feeling of the movie.
