As I started watching this show, it felt so familiar, I felt I had watched it before...

Then I found out the creator was the writer for Sanctuary and it all made sense. Basically the old Sanctuary premise was rewritten to become this.

This show was based on a comic series written by Steve Niles & artist Damien Worm.
