“Beach House” (*1/2 out of four) was a dreary story about a young girl (Emma Fitzgerald) on retreat at a quiet beach resort when a mysterious artist (Murray Bartlett) appears who knew her mother (Orlagh Cassidy) but she soon comes to suspect him of a terrible crime buried in both of their pasts. Dawdling melodrama moves like molasses but has no real story to tell. Film’s final surprise isn’t much of one. At least the beach scenery and surroundings are pretty and well-captured.
