Narcissim comes in all shapes and sizes. Why? people, men particularly feel the need to dominate a woman is because they are insecure within themselves. This movies fully demonstrates the socio pathic behavior of an insecure man, who is ruthless and manipulating. He will do anything to get his way even to the point of hurting the women he claims to love, drive her insane, just to keep her close.
In reality this never works, eventually the woman (or man) will see the truth of their signifcant other.
Controlling and dominating someones life will not only drive them crazy, but in the end resentment and lack of trust will set in and pile up towards feelings of anger and pain.
