“The Light Between Oceans” (*** out of four) was a moving story about a lighthouse keeper (Michael Fassbender) and his young wife (Alicia Vikander) who are unable to have children. One day, a baby washes up in a boat whom they adopt as their own but numerous complications arise when the child’s real mother (Rachel Weisz) enters their lives. Fascinating story of moral ambiguity and responsibility takes a while to get going but becomes more involving and thought-provoking as its serpentine story unfolds. Final half-hour is particularly shattering. Fassbender is rock-solid as usual. A solid showing for director Derek Cianfrance although this is no match for his last film “A Place Beyond The Pines.”
