I only saw that movie once - in the theater - and have never forgotten it.
My neighbor had an experience not too different from the movie. After she divorced she rented out a room in her house to a middle aged female who answered her ad. Took over 2 years to finally evict the deadbeat psycho. Worst part was the Sheriff informed her if she just changed the locks on her own and locked her out the psycho could probably have her fined and/or arrested.
