I just started watching Grimm a week ago, and I havent stopped. I never knew or seen any comercials for this show, so I didn't know about it, but when I saw Grimm on Prime, I wanted to try it out and I've liked it since the first episode. Having been a "Supernatural" fan for 15 years, If I would have known Grimm was a supernatural show, I would have watched it a long time ago. I truly wish they would restart it up, because i know a lot of people would watch it....
