NEW YORK -- You remember "Shutter Island?" Martin Scorsese's adaptation of the Dennis Lehane novel? An A-list B-movie homage about a war veteran sealed inside a Massachusetts nuthouse? You remember every hallway clattering like Samuel Fuller's "Shock Corridor?" Operatic visions of expressionistic gore? A hospital ethics committee certified by Josef Mengele?Well, the subtitular institution on "American Horror Story: Asylum" (FX, Wednesdays at 11 p.m.) makes that place look like the Mayo Clinic. Creators Ryan Murphy and Brad Falchuk vibrate on much the same frequency -- and they ratchet up Scorsese's Catholic-school Gothicism, and they ratched up the scenario, and they apply a no-shame high gloss to deliver wet kisses to cinematic trash.
