Grimm is an American fantasy police procedural drama television series created by Stephen Carpenter and Jim Kouf and produced by Universal Television for NBC. The series aired from October 28, 2011 to March 31, 2017, for 123 episodes, over six seasons. The series’ narrative follows Portland Homicide detective, Nick Burkhardt (played by David Giuntoli), who discovers he is a Grimm, the latest in a line of Guardians who are sworn to keep the balance between humanity and mythological creatures, known as Wesen. The series features a supporting cast, consisting of Russell Hornsby, Bitsie Tulloch, Silas Weir Mitchell, Sasha Roiz, Reggie Lee, Bree Turner and Claire Coffee.
Grimm was originally developed for CBS, but plans were canceled due to the writers’ strike. In January 2011, NBC opted for the series. It has been described as “a cop drama—with a twist… a dark and fantastical project about a world in which characters inspired by Grimms’ Fairy Tales exist”, although the stories and characters inspiring the show are also drawn from other sources. The series initially garnered mixed reviews from critics, though reception grew more favorably throughout the series’ run. The sixth and final season of Grimm premiered on January 7, 2017 and concluded on March 31, 2017.
