SERIES PREMIERE: Calling this a “premiere,” with the Acorn streaming service presenting yet another British import as part of its lineup, is really a stretch. That’s because this drama series, starring David Rintoul in the title role as a doctor establishing private practice after his stint in World War II, ran in the U.K. from 1993 to 1996. So this is a very golden oldie, even for loyal TV Anglophiles – but does offer some early looks at such familiar (to PBS viewers, anyway) British faces, and actors, as Annette Crosby and Ian Bannen.
