Although it is based on a popular Danish series, the show that AMC's "The Killing" most quickly evokes - with its brooding skies, ominous waters and complicated murder-mystery cast - is "Twin Peaks," a fact that AMC seems more than happy to leverage. "Who Killed Rosie Larsen?" is the show's promo, a direct homage, or rip-off, of "Who Killed Laura Palmer?" - a question that kept American audiences enthralled for two seasons (though in hindsight it feels like more).
