TNT's The Alienist ran for two extremely popular seasons, and now there is a lot of anticipation for season 3. Debuting in 2018, The Alienist is set in late-19th century New York and follows a psychiatrist who assembles a crack team to track a ruthless serial killer. Noted for its high production values and interesting approach to historical fiction, The Alienist brings to life the Caleb Carr novel of the same name, as well as its follow-up. Besides its gripping mystery plots, the series also uses its historical setting to comment on society both in the past and in the modern day.
