Couples Retreat (2009, USA) C-113m. *½ D: Peter Billingsley. Starring Vince Vaughn, Jason Bateman, Faizon Love, Jon Favreau, Malin Akerman, Kristen Bell, Kristin Davis, Jean Reno. Silly comedy about three diverse but befriended couples, hwo make a trip to Bora Bora for a partnership therapy. Once there, they are subjected to all kinds of idiotic therapies. Some laughs, but script (co-authored by Vaughn and Favreau) is overlong and dull.
