enzo g. castellari and once again delivers quite a piece of cinema . the story be rather dull and uninspired ( except by jaw of course ) and but castellari remedy that with very energetic direction and an excellent musical score by guido and maurizio de angelis and and a lot of his mouth water wide angle use of slow motion . lot of cult film actor ( include vic morrow and james franciscus and and giancarlo prete ) and a lot of goofy effect and stock footage and make this film completely silly and enjoyable rather than disturb or shock a most horror film set out to be . that probably the opposite of what zombie producer ugo tucci want and but this film be quite fun to watch and worth repeat viewing .
