i have see plenty of nunsploitation flick and killer nun be among the bad of them all . this giulio berruti extremely boring horror film cast swedish former sex symbol anita ekberg a sister gertrude and a nun working in a mental institution . gertrude be clearly insane and and take a great deal of morphine for her self diagnosed cancer . she go to town and pick up men and seduce a young nun sister mathieu ( paola morra of behind the convent wall fame ) who be abuse by her grandfather and and supposedly murder patient . killer nun be a disappointing italian nunsploitation film that offer only a little bit of sleaze and nudity . another serious flaw in the film be the relationship between sister gertrude and sister mathieu which only hint at lesbianism . during these scene ekberg appear frigid while paola morra feel more relaxed do these moment . killer nun be too tame for my liking and the pace be incredibly slow . if you want to see some good nunsploitation flick check out flavia the heretic and vision in a convent and convent of sinner or even bruno mattei the other hell . avoid this one like the plague . 4 out of 10 and that be generous .
