“Serenity” (** out of four) was a disappointing thriller about a grizzled fishing boat captain (Matthew McConaughey) who encounters a woman (Anne Hathaway) from his past and they conspire to free her from her loveless marriage to her loutish husband (Jason Clarke) by killing him but naturally all is not what it seems. Starts off intriguing but story goes so far afield and becomes bewildering, pretentious, and extremely weird that by the time of its climax it winds up empty. McConaughey’s usual charisma and sleek photography on the island of Mauritius help to keep this watchable. Hathaway is miscast as a femme fatale.
