Grimm is a great show and I absolutely love every episode of the 6 seasons, I am sad that when the season finale of Season 6 was screened and will miss the interesting plots and characters. The series could have been extended 1-2 seasons to explain the royals more in depth and the development of the daughter Diana who is not a Grimm but ends up doing a Grimm's job in the ending of the last episode. More stories could be told for Capt Renard's vision of the mysterious man who haunts him in the earlier episodes of Season 6. I guess the producers ran dry of new ideas or just wanted to end the series when it is still popular with viewers but still most series have more than 10 seasons just look at NCIS,. Wonderful series and highly recommended for viewers who like a bit if fantasy and somewhat dark storyline of creatures and magical potions.
