Penny Dreadful goes beyond being a dark drama; it transcends this genre, blending it with a supernatural force compelling you to tune in each week to discover what happens to our intrepid troupe of adventurers. In “The Nightcomers,” this entire episode is a dedicated flashback to Vanessa Ives’ (Eva Green) past and how she learned who she is captivating you from beginning to tragic end. Special guest star Patti LuPone owns every single second she’s on screen with a powerful performance. She’s nearly unrecognizable as the old crone known only as “the Cut Wife of Balandry Moor.”
