This is typical psycho obsession with love movie. Like many other lifetime movies, but with worse ending. There is lack of story or details. But there are realistic and natural parts. What can we observe in this movie is that where there is obsession+rejection, there are consequences, like in any other areas of life, not just love. While we can't learn any specific lesson from this movie, because some people will just not give up or are unpredictable. We at least can learn that we are half responsible for what happens to us from any criminal or psychopath. Best thing we could do is to as early as possible take maximum distance, security, precaution. Once we get close it is too late. But even that is just enough to protect ourselves only, and not other possible victims. This raises awareness of obsessions, and consequences of rejection. We should be more aware of any obsessions, psychos, wounds, crimes, and weaknesses.
