Doc Martin

This is a question as well as a comment. Following the final episode of the Doc Martin series just shown by the Australian Broacasting Commission was the caption "Dedicated to John Coleman". I can find no reference to John Coleman on the Doc Martin website. I am guessing he was one of the writers. Am I right? By the way, I loved the series, but one or two things bothered me. The plots were interesting enough and the most of the characters were beautifully drawn, but to some extent some of them were a bit two-dimensional. For example the professionally super-efficient Doc Martin was so rude to everyone that one could hardly believe that any of his patients would ever come back for more. The policeman was (at least until the final episode) unbelievably inept, if not dim-witted. Sorry but I couldn't accept the snake bite episode, when the Doc displayed more patience with the mad forest ranger than he had with the entire village of (reasonably) sane people. The final episode was by far the most believable and the best. On the credit side I found the casting perfect, the setting idyllic and the photography exquisite. The whole thing was so beautiful it made me wonder why I ever left the dear old place. Is there to be more? Dennis Mitchell.
