Acorn Media recently released Doc Martin Collection: Series 1-4 on DVD. While parts of this set have previously been available separately, this is the first time the whole series (thus far) has been released in one collection. In the set are nine discs with thirty episodes, including the feature-length Christmas special that aired after Series 2. This show is on ITV in the UK and airs on PBS in the states.
Doc Martin stars Martin Clunes (Demob, British Men Behaving Badly) as the titular character, a surgeon who finally sees his patients as people, not just bodies, and can no longer stomach the sight of blood. As such, he packs up and moves to the small seaside town where his Auntie Joan (Stephanie Cole, Coronation Street, Tenko) resides, Portwenn, and becomes their local general practitioner. Doctor Martin Ellingham has a few chips on his shoulder, and thus clashes with the colorful locals, finding their personable ways annoying. He especially doesn't not like the nickname Doc Martin, which they bestow on him immediately upon arrival.
Clunes handles the comedy beautifully, both physical and subtle. The character is a little like House, M.D., though not quite as abusive, and a little more accepting of his flaws. No drug addictions here. A particularly funny recurring gag is the dog that seems to come with the house and practice that Martin does not want.
In the first series, Martin repeatedly makes mistakes that alienates all of the locals, who in a group mentality, cut him off and refuse to deal with him. Once he solves the medical conundrum and saves some lives, they realize he's not so bad, and open back up to him. This becomes less drastic as the series goes on, and it appears the townspeople are accepting him and ribbing him as one of their own.
The town itself is a bit like Stars Hallow from Gilmore Girls, with each recurring character having their own eccentricities and position within the larger group. They treat their town as their own, self-sustaining world, with many having little use to travel beyond its borders, as there is plenty to get out of life staying right here. That being said, it's also realistic, and the younger people do like popular music and actors, so it's not completely isolated. And the scenery is beautiful.
