Doc Martin Bamford, an amiable, dope-smoking GP in a Cornish fishing village, appears in the movie "Saving Grace" and two made-for-TV prequels that explained who he was and how he got that way. This first time out, he's an obstetrician not a surgeon, he doesn't lose it at the sight of blood, he's a beaming, rubber-faced cherub not a scowling, sharp-tongued Aspie--that's Doc Martin Ellingham, as thoroughly reimagined for the long-running series by Dominic Minghella (whose name, as somebody on an IMDb bulletin board pointed out, is an anagram of "Ellingham"). Too much info? Doesn't matter. This "Doc Martin" is the first of the TV prequels, not as clever or as original as the series, perhaps, but perfectly charming and involving all the same. Good work by Tristan Sturrock (he's in the series as well) as a laid-back lobsterman and Neve McIntosh as a witchy tavern singer (she's not, more's the pity, eh?).
