“Mr. Harrigan’s Phone” (**1/2 out of four) was an imperfect but endearing melodrama about a lonely teenager (Jaeden Martell) who befriends a reclusive billionaire (Donald Sutherland) who soon dies but thereafter the teenager starts receiving texts from his phone which sets the stage for an onslaught of twists and turns in his life. Story is meandering and plodding at first but becomes more involving as it veers from coming-of-age story to elements of Hitchcock thriller and also a vengeance drama. Mitchell’s likability helps compensate for film’s rough changes in structure and mood. You’d never guess this was based on a short story from Stephen King but this is overall one of his better film adaptions in a while and is in the pulp vein of “Stand By Me” and “It”.
