The wife of in this movie is a real piece of work. She cheated on her husband, gets sick, receives a lot of care from him and friends and then bye bye. What I would say is that she got her hands in cookie jar and faced no consequence of her actions..unless we consider terminal illness as some punishment. Fair deal, I'd say.
In reality, any sane man should leave such woman immediately upon cheating..but wait whom I'm kidding. Divorce laws favor women, she gets hefty divorce settlement and juicy alimony for decades. Such cheaters really deserve such illness. See the 5 stars are mostly given by women. "Oh the good husband" as they say.
