There have been so many engrossing dark TV series that took viewers on mind-bending journeys and truly played with their heads. While modern television has embraced much darker and more sinister stories in recent decades, it takes a truly great show to bury underneath the surface of a series narrative and deliver philosophically rich stories that strike a chord for their deep, probing themes that leave a mark on viewers consciousness well after the credits have rolled. A thought-provoking series that can play with viewers’ expectations often marks the difference between a simply good show and a truly great one.
