While the premise of the show isn't completely original they do a GREAT job of masking this. I started watching this show after it was cancelled which is a d*mn shame. I had never heard of it until I stumbled upon it on Hulu. Shame on TNT for canceling such a great show after they clearly didn't advertise it very well. If you like Supernatural, Warehouse 13, Charmed, shows like that check The Librarians out
