“The Eternal Daughter” (* out of four) was an eternal bore about an artist (Tilda Swinton) and her elderly mother (Zinnia Davies-Cooke) who return to their family home and discover long-buried family secrets that threaten to destroy their present lives and thus their future. You keep thinking something significant will happen but it never does as film moves like molasses and goes nowhere. Even the usually excellent Swinton is stiff and dull. A real disappointment from talented writer/director Joanna Hogg.
