“Submergence” (** out of four) was a dreary melodrama about the relationship between a Scottish soldier (James Macavoy) and a marine scientist (Alicia Vikander) told in flashbacks as he is held captive in a jihad prison and she is on an ocean expedition. Attractive scenery and talented stars do their best to enliven the proceedings but they’re submerged by film’s meandering pacing and storyline. Fans of director Wim Wenders (I’m not) may find more of substance here but it’s one more of his works that is visually pretty but emotionally empty.
