This week, two of last year’s failed series, NYC 22 and ¡Rob!, make their way onto DVD thanks to Amazon’s Manufacture-on-Demand program. Plus, it’s a British invasion, with loads of UK titles hitting store shelves this week. Getting Blu-ray and DVD releases are Being Human: Season 4, House of Cards Trilogy and Merlin: The Complete Fourth Season. And coming to DVD only are Life’s Too Short: The Complete First Season, Twenty Twelve: The Complete Series and Waking the Dead: Complete Season Seven.
