Last week, we reported that NBC had ordered two additional scripts for their new Friday night series, Grimm. It seemed that the peacock network was playing it safe, waiting to see when the ratings would level off. What a difference a week can make.

This evening, the peacock network announced that they’ve ordered a full season of the TV series. What’s more, they’re also giving Grimm a special airing in the Thursdays at 10pm timeslot. That will air on December 8th and another original installment will follow on Friday, December 9th, in the regular timeslot.

Starring David Giuntoli, Bitsie Tulloch, Silas Weir Mitchell, Sasha Roiz and Russell Hornsby, Grimm has been the only successful new drama that the network has had this season. The Playboy Club was cancelled after three episodes and Prime Suspect will sign off after all 13 episodes have aired.

Four episodes of the supernatural series have aired so far and have been averaged a 1.8 rating in the 18-49 demographic and 5.8 million total viewers (per the final national ratings). It’s the seventh highest-rated scripted series on the network this season (out of 14). It nearly doubles the demo number of lead-in Chuck.

Grimm started the season with a 2.1 in the demo and 6.56 million viewers but declined in weeks two and three. Last Friday’s installment held steady at a 1.6 in the coveted demo and it would seem that NBC believes that a sign the ratings have leveled off. Time will tell.

What do you think? Do you like Grimm? Do you think the ratings have leveled off? Will the series continue to sink or will it rise? Is Thursdays at 10pm a better timeslot?
