>The Vineyard, a new reality series on ABC Family, doesn’t have a thought in its head. But why should it? Set on Martha’s Vineyard, it shows us the romances, feuds and heartaches among the young crowd, both residents and summer interlopers. None of it feels very spontaneous, but the cast is great-looking and has no reason to be shy of beachwear. It’s Jersey Shore toned up as an Abercrombie & Fitch campaign.
