Doc Martin 9pm, ITV
The summer holidays are over, but no need to worry as the sun almost always shines in Portwenn, albeit sometimes on bittersweet scenes. Here, in a new series, we find reconciled Martin and Louisa raising baby James Henry. Louisa: “Do you think he likes me?” Martin: “Who knows? I didn’t like my mother, does it matter?” Elsewhere, daft constable Joe prepares to marry flighty Janice, in a ceremony to be conducted by “a vicar with learner plates on”.
