Never played The Witcher, but I've been a fan of Supernatural since it first aired. I'm annoyed that the CW and Hulu apparently no longer have a deal, because that's how I was able to keep up with the show as it was airing. Now I'll have to wait until the current season shows up on Netflix net fall. A couple of the seasons' story arcs are a little weak, but over all, I really enjoy it.
