Originally announced as a limited series, the ABC drama Black Box will stay that way, with the network opting not to order additional episodes. All 13 produced episodes have aired. Black Box, starring Kelly Reilly as a top neuroscientist who appears to have it all but is constantly haunted by her own struggle with mental illness, got off to a slow start in the Thursday 10 PM slot, opening with a 1.5 rating in adults 18-49. It was subsequently shifted to the less trafficked 8 PM hour where it recently ended its run with a 0.7 in 18-49.
