Plenty of shows–See Rosewood–have done worse after they’ve lost a good lead-in.
Of course, it should be noted that Taken is airing after high performer The Voice on NBC.
A good lead-in can help the numbers for a new show considerably, and if The Voice continues to do well, that should bode well for Taken, as well, in the weeks to come.
The real testament will be if NBC signs on for a second season of the drama and shuffles it into a new timeslot.
