The
Monthly Film Bulletin declared the film as "a genuine curiosity" with its "bizarre eroticism" concluding it was "not uninteresting, but unfortunately has the effect of giving some of the digressions rather more weight than the control narrative." Writing for
AllMovie, Robert Firsching rated the film three stars out of five, and found it difficult to place in a genre, considering it a mix of
giallo, science fiction and
drug film elements. Firsching described the film as "deliriously strange", noting that it was "a must-see for genre fans"; he also stated parts of the film resemble
David Lynch's
Eraserhead. Luis Canales, in his book
Imperial Gina, reports that the film "received lukewarm criticism" upon release, although he writes that both Questi and Lollobrigida were pleased with it. Gian Piero Brunetta, author of
The History of Italian Cinema, considered the film to be "worth remembering", comparing it to the works of
Luis Buñuel and
Michelangelo Antonioni. Brunetta felt the film held several thematic undercurrents, dealing with the conditions of farm labourers and the changing social attitudes towards the class system in Italy. In March 2015 the film was re-released as part of the Malastrana Film Series in the event
The Killer Must Kill Again!: Giallo Fever, Part 2 as part of the
Anthology Film Archives in
New York City over
Malastrana Film Series on
35mm. ==Footnotes==
