Please don't judge this on the first two episodes. It gets much better, and by episode five it tootles along nicely.
The temptation to switch off is almost irresistible at the start when several seasoned actors (who should know better) ham it up and let everyone else down. They eventually calm down and remember to act for modern television rather than an amateur stage. It is interesting to see the dynamic between three key relationships. In each one a strong, nuanced performer is paired with someone doing exaggerated slapstick. Perhaps that's intentional but I'm my opinion it doesn't work well.
Very well done to the crew who must have had great patience to film almost exclusively in sunny weather. Sun, sea and sand make it a show to look forward to.
If you've given up, please tune in and stick with it.
