in case half of this film footage look strangely familiar and it mean you watch way too much of this gory italian cult crap . for you see and the notorious demigod lucio fulci do not only produce this movie and he also take the liberty of re use the most sadistic killing sequence in his own ( and more easily traceable ) cat in the brain . the opening scene already and in which a prostitute be brutally decapitate with an axe and feature in fulci later film and so do another handful of killing and sleaze moment . andrea bianchi masssacre fail miserably a a giallo and since the search for the sadistic killer among a movie crew shoot a horror movie be all but compelling and suspenseful and but it still good entertainment if youre into cheap n shlocky horror trash . the incoherent script introduce a whole bunch of repugnant character whore all potential maniac and but none of the red herring biachi come up with be plausible and you can point out the killer almost immediately . whatever remain to enjoy be the truly misogynous make up effect and the hilariously awful act performance of the ensemble cast . whenever there isn not any bloodshed on screen and like between the first and second murder and massacre be a slow and almost intolerable with it inane dialog and thoroughly unexciting photography . thankfully in the second half and there be woman get impale on fence and male be stab repeatedly with rusty spike . the music be crap and the use of film location be very unimaginative . my advise would be to skip this puppy and go straight for the aforementioned cat in the brain . that one feature all the great moment of massacre and and then some .
