NBC had big hopes for their all-drama Thursday night schedule. Unfortunately, the ratings have been dismal and now the network has cancelled their new drama, Allegiance, after five episodes.

On the Allegiance TV show, Katya and Mark O’Connor (Hope Davis and Scott Cohen) and their daughter Natalie (Margarita Levieva) are part of a dormant Russian sleeper cell that has just been reactivated. Their mission is to turn their son Alex (Gavin Stenhouse), an idealistic CIA analyst, into a spy. Others in the cast are Morgan Spector, Kenneth Choi, and Alex Peters.

The series debuted on February 5th to a dismal 1.1 rating in the 18-49 demographic with 4.98 million viewers. Then the numbers got even worse after that, hitting lows with a 0.7 in the demo and 3.32 million viewers.

NBC’s eight-episode mini-series The Slap has also been doing very poorly and recently relocated The Blacklist has been taking a beating opposite Scandal on ABC and with no lead-in support.

The network has now decided to pull the plug on Allegiance. They’re moving The Slap to 10pm for the remainder of its short run and will fill the 8pm timeslot with special editions of Dateline NBC.

It’s unclear how many episodes of Allegiance will be left unaired or when/if they will see the light of day. Whatever happens, it looks unlikely that the show’s relatively small audience will get any kind of closure.

What do you think? Did you like Allegiance on NBC? Do you think that the network should have cancelled this series? Should they air the remaining episodes?
