Braindead (1993) on Netflix

In New Zealand's peaceful town of Wellington, Lionel Cosgrove--an oppressed bachelor who is still living with his despotic mother, Vera--has finally found his soulmate: the kind grocery store clerk, Paquita. However, before long, things will take a turn for the worse in Lionel's already messed-up world, when Skull Island's vicious Sumatran Rat-Monkey bites Vera after a visit to the local zoo. Now that Vera's got the "bite", the virulent infection is rapidly turning her into a puss-squirting flesh-eating living dead, and the volatile situation is bound to get out of hand, as an ever-growing collection of dead bodies and other stimulant-enhanced zombie misfits start to cram Lionel's basement. Poor Lionel--whether you like it or not--you need to man up and clean up the mess; moreover, summon up the courage to confront your decomposing mummy, and the family's ugly secret. Nevertheless, has Lionel what it takes to save the day, and get the girl?
