Italian horror films from the eighties formed their own distinct category, encompassing everything from intense giallo movies to supernatural tales and cannibalistic narratives—experiences that were both frightening and captivating. Here, Argento’s writing combined with Bava's direction results in a film centered on demons brought to life. The execution is effective; for instance, a woman sustains a facial scratch from a mask, an event mirrored within the movie itself, recurring multiple times and reflecting real-world occurrences. Disorder quickly unfolds as more individuals become affected, while those we’ve come to care about attempt to survive. There are numerous graphic scenes featuring realistic special effects—depictions of severed heads or limbs with copious amounts of blood in various colors like red, green, and yellow. Once fully engaged, the film provides a genuinely exciting experience, and the eighty-eight minutes pass quickly.
