I didn't know when I first heard of it and first saw people I followed mentioning they were watching it. In fact, for a while, I got it confused with a standard American police procedural that didn't have any appeal to me, and I was very puzzled as to why it seemed to be developing fannishly. Then bonibaru showed her vid at a con--I missed seeing the vid, but my friends who did all told me you HAVE to watch this show, it seems like something you'd like, and IIRC at least one person said it seemed to have fantasy elements in it, but that info didn't stick with me until ranalore posted about the show. Then I knew it was SF/fantasy and was ready to dive in.and have not surfaced since :)
