The ax has fallen for a veteran prime-time drama series airing on NBC. Deadline.com reports that the upcoming sixth season of “Grimm” will be the last for the supernatural crime drama.

Season six will premiere Jan. 6, with the show running again on Friday nights but airing an hour earlier than previous seasons, at 8 p.m.

“There was an alarm raised in April when ‘Grimm,’ whose first five seasons consisted of 22 episodes each, only received a 13-episode renewal for Season 6,” Deadline notes. “The series was left on the bench for the first time. Except for 2012 when it launched following the Summer Olympics, ‘Grimm’ has been debuting just before Halloween.”

The report adds: “Last season, the supernatural procedural averaged  a 1.6 most current adults 18-49 rating and 6.0 million viewers. That was down from the Season 5 averages (2.0, 7.1), but ‘Grimm’ still ranked as one of the highest-rated scripted series on Friday despite being a self-starter, with very little lead-in support.”
