These women are not examples of normal ex-wives. They have the money and fame to go the extreme in exacting revenge on their sorry ex-husbands.
The aim of the show is to help those who had been through a divorce, not that they should be examples of a divorcée but they're there to use their money and fame to help these people who has been through a bad phase of their lives. this show shouldn't be thrown to trash because this would actually help other people.
