I can't understand the negative reviews. I love the time period, it adds to the dark foreboding atmosphere that can't be captured in a modern era. The acting is superb. The story line frightful, yet realistic. Geraghty as Roosevelt is wonderful. I watch each episode a couple times. I really love the series, but like many other shows I've enjoyed, many others didn't share my enthusiasm and they were eventually canceled. Hopefully, that won't be the case with The Alienist.
