Writer Will Honley (“Bloodline,” “Escape Room: Tournament of Champions”) has a strong idea for horror in “Blood,” examining the extent of a mother’s love when she’s forced to turn to macabre solutions to solve unreal problems. Unfortunately, Honley only gets as far as a short story with the material, straining to stretch the particulars of the concept to a feature-length run time. Director Brad Anderson (“The Machinist,” “Vanishing on 7th Street”) attempts to conjure a dark mood for the endeavor, which plays with mysterious happenings and grim developments in health and home, but there’s not a lot of dramatic meat on these bones. “Blood” gets pretty far with a first half devoted to grotesque situations and marital hostility, but the production can’t sustain such mystery, eventually slowing down to a full stop as the screenplay loses interest in developing the central crisis.
