The saga of the tormented Dollangangers comes to an end in “Seeds of Yesterday,” in which the family continues to coexist miserably. Also starring Carpani and Lewis, the film follows Cathy’s two adult sons, Bart (James Maslow, “Big Time Rush”) and Jory (Anthony Konechny, “Fifty Shades of Grey,” “Godzilla”), half-brothers with little in common whose lives are fueled by deeply troubled relationships, dark secrets and misfortune that come to a head in a way that will haunt the family and its progeny forever.
