Considering the enigma of Emily Dickinson’s life, her reclusiveness, her being largely unpublished while alive and the posthumous popularity of her work, the poet is an ideal subject for a film biography, something that might ignite an image of her in the audience’s imagination. Terence Davies, that most sensitive and, himself, poetic of artists, would seem an ideal person to accomplish that task. So the fact that “A Quiet Passion” doesn’t succeed, seeming to push Dickinson further into darkness — or more accurately, gloom — is greatly disappointing.
