a crop dust machine from the agricultural pest control be emit ultra sonic wave that be re animate corps . a lot have say this be underrated and grant it overlook and it atmospheric and moody and have great location and be genuinely creepy . however and it share more with fulci than romero . the acting be just about competent and bad dubbing and it have an eerie musical score and a number of suspenseful sequence but it far from an iconic or cult zombie film . i watch it under the title of let sleep corpse lie but whichever name you see the film under do not be mistake or mislead and it an average zombie horror movie of it time with nice cinematography . that say and it a lot good than the low budget dtv zombie film that there no shortage of at the moment .
