I just watched the housemaid

This movie was crazy as hell!! In the beginning I thought it was a series like that other show about the nanny babysitting the dead baby but it was a movie about a housemaid cleaning job , I was thinking why would a hot girl like that want to be a cleaner? But there was Reason for it and the whole time I am thinking how dare this housemaid seduce and steal the wife's husband?? Then the plot twist at the end that was crazy all in all I would give it 7 out of ten just cause they overdid it at the end and it turned to something else.
