I am often amazed at how frequently private islands or private island resorts are the setting for m0vies. Islands provide the perfect backdrop for adventure, romance and horror.  The other night I decided to rent Couple’s Retreat after noticing it’s idyllic Bora Bora setting in the previews. The movie stars Vince Vaughn and involves four couples venturing to Tahiti for a little R&R and reluctantly, couples therapy. Unfortunately, the scenery was the best part of the movie, which otherwise was a bit of a stinker.
