Television letdowns of 2013:1. Murder as installation art. This has become a real personal peeve, as shows like NBC's "Hannibal," Fox's "The Following," AMC's "The Killing" keep treating a crime scene like it's an MFA thesis exhibit. Murder is horrible enough all on its own ("Broadchuch" made it as simple as a boy's body at the foot of a cliff); it doesn't need art direction, wires, costumes, paint, glitter, branches, antlers, feathers, etc. The idea of the killer-as-curator is a desperate (and now cliched) byproduct of writers who think they need to outdo other crime shows in the gore department.
