The problem is that it was written as a "one series" program with no extra series planned.
Now the writer has to add enough interest for a second series, which is difficult.
My guess is it will be disappointing.
p.s. My wife and I went on holiday to West Bay in Dorset last year where much of it was filmed and it was fascinating to walk round the areas they filmed in.
The "cliff" is there, as is the newspaper shop, the harbour, the police station, the caravan park and so on.
