The Gores' experience at Marriage Encounter was thoroughly recounted by Texas Monthly, and seemed to be as emotionally intense as Hulu's adaptation makes it out to be. Couples were reportedly encouraged to be open with each other, and, as shown on "Candy," the Gores returned from their weekend rejuvenated and more in love than ever (although in reality, it was Allan Gore who first suggested the retreat, not Betty Gore).
As mentioned on the show and in Texas Monthly's reporting, the Montgomerys also tried Marriage Encounter, but didn't have the same success that the Gores had.
