Nisha Ganatra (The High Note) tries a tried-and-true formula with a slight twist in Late Night. The Emma Thompson (Howard’s End, Sense and Sensibility) dramedy focuses on her career as an acclaimed late-night talk show host who may be nearing the end of her career after plummeting ratings in recent months/years. Flanked by an all-white male writing staff, Katherine Newberry’s (Thompson) material has become predictably stale.
