The Durrells

The Durrells (known in North America as The Durrells in Corfu) is a 26-episode British comedy-drama series loosely based on Gerald Durrell's three autobiographical books about his family's four years (1935–1939) on the Greek island of Corfu. It began airing on 3 April 2016 and ended on 12 May 2019. The series is written by Simon Nye, directed by Steve Barron and Roger Goldby, and produced by Christopher Hall. Lee Durrell, Gerald Durrell's widow and director of the Durrell Wildlife Conservation Trust, acted as consultant. The series was partly filmed at Ealing Studios and Twickenham Studios in London.
Story.
The series begins in 1935, when Louisa Durrell suddenly announces that she and her four children will move from Bournemouth to the Greek island of Corfu. Her husband died some years earlier and the family is experiencing financial problems. A struggle ensues as the family adapts to life on the island and a shortage of money. Despite a lack of electricity and of modern sewage systems, Corfu proves to be a cheap and earthly paradise.

Reception.
Reception to the first episode was positive, with Gerard O'Donovan ("The Telegraph") calling it "a series that's not only sun-drenched and liberating, but also catches its source material's high good humour without labouring it and weaves an authentic sense of the innocent exoticism of the original," before awarding it four stars.
The opening episode averaged just under 6.4 million people and was watched by 29% of the audience over the hour, including those watching on British television network ITV's +1 channel, and was the biggest drama launch of any channel so far in 2016 and the most-watched show of the day (including +1). Following a seven-day catch-up period, the figure aggregated to just under 8.2 million people. Citing the show as its "best rating new drama of the year and its highest rating new show since September 2014", ITV recommissioned the show for a second series on 15 April 2016. Over the course of the first series, ratings averaged out at 6.9 million viewers.
