Some comments lament the movie has changed from the book (especially the ending). I heard a Greta Gerwig interview today where she explained she studied Louisa May Alcott and found out Alcott, in actuality, was pressured by her publishers, to marry Jo at the end of the book. Gerwig wanted to honor Alcott by ending it the way it really was meant to be. This knowledge made the movie so much better for me.
