“RATCHED”

(Streaming on Neftlix) What made Nurse Ratched evil? The cruelly stern psych ward nurse from Ken Kesey’s novel “One Flew Over the Cuckoo’s Nest” (whom Louise Fletcher brought so memorably to life in the 1975 film) gets an elaborate, eight-episode prequel treatment from Ryan Murphy and company, with Sarah Paulson as a younger Mildred Ratched, who proffers her services at a seaside asylum in 1947 where all manner of ill-considered treatments are taking place. Come for the trepanning; stay for Judy Davis’ performance as Ratched’s bitter rival, Nurse Bucket. (Sharon Stone, too, as a disgruntled client.)

SAEED ADYANI/NETFLIX Sarah Paulson as Mildred Ratched and Alice Englert as Nurse Dolly in “Ratched.”
