It’s not easy being the village GP in Portwenn as once again, Dr Martin Ellingham is the centre of calamity, drama and lingering gossip. It seems the grumpiness is acute and chronic. The bad mood is no longer in remission. All the symptoms are there, the truculence, the tactlessness, the caustic take on everyone and everything. ‘Doc Martin Series 3’ follows the ongoing accidents, emergencies and comic mishaps in Portwenn as the good doctor bumbles through life, all the while trying to pursue his burgeoning but seemingly ill-fated romance with headmistress, Louisa Glasson.
