Poetic and profound

Kenneth Lonergan, who wrote the movie Manchester by the Sea, shapes his work from loss, disillusionment, small-mindedness, hesitation and superficiality, all the forgettable detritus of life. The Starry Messenger is about Mark, a disappointed astronomer aged 52, who gives public lectures at a city planetarium. He loves his subject even though it let him down and every week he tackles the daft questions of his pupils with superhuman patience.

The same two pests always raise their hands. One is a burly misanthrope who disbelieves all experts, the other is a high-flying oddball who craves attention. Mark starts a slow-burn affair with Angela, a single mum who needs a role model for her nine-year old son: an expert on the stars and inter-planetary travel is just the ticket. Back at home Mark is cared for by a kindly wife who prattles about sofa beds and dry cleaning. In the basement lurks a teenage boy miserably thrashing at an amplified guitar.
