I am hard-pressed to explain the praise heaped on this movie, and must sadly choose the obvious. This film would never have been touted as it has if it were made by someone other than Arthur Miller's daughter/Daniel Day Lewis's wife.
Of the film's three vignettes--domestic violence survivor, conflicted editor, and confused runaway--the second is most telling. Greta, the failure to her family, craves success and power in the literary world and only needs to have her innate talents recognized to do so. Her skill is "trimming the fat" from others' writing. However, Ms. Miller seems to have had no such attention paid to her own work. The incessant and intrusive voiceover dialogue, I assume taken directly from her collection of short stories, features pseudo-deep lines that made me literally laugh out loud.
In addition, I found many of the camera tricks and plot devices amateurish and the characters shallow and essentialized. I cannot recommend this film, which basks in its own specialness and its claims to gritty reality. Ms. Miller is a tourist in the lives of the struggling women she attempts to portray.
