10. Death Nurse -- Nick Millard
This will show dad that a movie can be a whole lot worse than The Incredible Melting Man, this Nick Millard is one dull uninspired director, and it's a blast watching his full on baddies, he made half decent horror films in the 70s but this one here is low even for him, and good news it has a sequel, and another related film, i'm missing some of them though so they'll be spaced apart, you need to savor this stuff!!
Murderous, overweight nurse Edith and her brother run a medical clinic out of their suburban home: they take in patients, kill them, and continue to bill the state for their care. But a nosy county inspector threatens to complicate this foul family business.
