It's nothing like "Doc Martin.
I've been thinking about this, trying to work out why it's so bad. As you have already pointed out all the names are the same, even the location, Port Wenn.
All I can come up with, is that the cast watched one or two episodes of the original and tried to copy the mannerisms of the original cast. And failed. They all come over as a little lifeless, bored, limp insipid copies of the original characters.
I never liked Bert Large, as that character annoyed the heck out of me and (my opinion) was the weakest part of the show (or was just written badly).
Just had a look, turns out the French made a version of it as well, which ran for four seasons. Still called Doc Martin, but he's Martin Le Foll. None of the other character names seemed to have survived.
