The X Effect was a short-lived reality dating series in which exes were reunited.
The show looked at the current and former relationships to determine whether or not individuals wished to recapture a former love or continue nurturing a new relationship. During the show, the two exes would spend a weekend at a resort hotel. Each couple was presented with opportunities to rekindle their former relationship, through participation in romantic activities. While they were on their "dates", they were covertly watched by their current partners, referred to as "the others" or "O's". At the end of the weekend, the exes had to choose between their old or new partners.
