If Greta Gerwig makes a movie, go watch it. Long rising as an actor (2012’s “Frances Ha,” which she also co-wrote, 2016’s “20th Century Women,” etc.), she has become a force as a writer/director. Her 2017 debut, “Lady Bird,” was spectacular. With “Little Women,” she shows off new skills. She achieves the Victorian period, takes the often-duplicated story and moves a new, modern audience to laughter and tears. Enjoy the return to the Oscars, Greta.
