The incompatibility of several Married At First Sight season 18 couples has sparked accusations that producers are intentionally stirring up drama rather than creating healthy marriages. The season features five couples who, after having no luck finding love on their own, agreed to be matched with an unknown partner by relationship experts. While the experts should have carefully combed through applicants to identify potential soulmates, some of the Married At First Sight season 18 matches left viewers scratching their heads. Many couples hit it off on their wedding day, only for their hopes to unravel as they settled into married life.
