Veronica Callahan's defibrillators have been shut down. NBC's first-season drama Mercy, like its extreme counterpart Trauma, has been canceled. I'm unsurprised with both decisions but only disappointed with Mercy. Taylor Schilling was irreverent but sincere in the lead role, Jaime Lee Kirchner won me over as Nurse Sonia, and Michelle Trachtenberg seemed poised for a full mainstream takeover in her first big network role. And to think how excited this cast was when they found out they were picked up for a back nine -- at a strip club. [THR]
