When Justina Machado returns home to her native Chicago, she barely recognizes it. Machado grew up in Chicago’s inner city, in the neighborhoods Lincoln Park, Humboldt Park and Logan Square — all of which she says have been gentrified. Gentrification is a catalyst for Machado’s new dark comedy series “The Horror of Dolores Roach,” debuting Friday on Prime Video. She plays the title character, a woman who has spent 16 years in prison and doesn't recognize the New York neighborhood she once called home. After opening a massage parlor, Roach resorts to murder to defend herself. It's the first lead role for Machado.
