The horror genre is filling up. The Walking Dead and American Horror Story lead the pack. Big networks are dabbling with Hannibal and Constantine. The new wave includes Z Nation, The Strain and Penny Dreadful. The latter has a trifecta balance of drama, thrill and horror. Plus a star-studded cast to boot: Timothy Dalton, enough said. Also Eva Green and Josh Hartnett. The history, fiction and overall British context make it a great world and setting to dive into. Characters come to life, origins are explored and the horror ensues.
