The classic Grimms' fairytales come to life like never before in this dark and imaginative series. Portland homicide detective Nick Burkhardt (David Giuntoli) discovers he's descended from a long line of "Grimms," who are charged with keeping balance between humanity and the creatures of myth. With newly awoken abilities to detect the evil lurking among us, Nick struggles to keep his old life separate and safe as he becomes ever more entrenched in the ancient rivalries of the Grimm world.
Very, very formulaic. There are a couple of subplots to make each episode slightly different from the previous one, but in essence once you have seen one you have seen them all. I'm not even sure that all the tales alluded to were in fact written by the Grimm brothers, but then my childhood was a while ago.
