Cathy’s Curse (1977)

A man and his daughter have a car accident and perish.  Years later, the man’s son moves back to the family home with his wife and their 8 year old daughter, Cathy.  Cathy gets all sorts of powers including being able to blow things up and telekenesis.  This movie is definitely in the genre of medium quality, medium gory, 1977 midnight movie.  Rated R
