Dont be put off by the assisted dying storyline. This is brilliant . Its moving particularly in the early episodes but then turns into a twisting storyline. All the actors are great but Lyndsey Duncan is superb as Phil. It also features a cast in their 70s and at the heart is a love story of love lost between Phil and Ken, I have not enjoyed a drama as much in ages , well done everyone . Filmed in Bristol , Clevedon and around Somerset .I think the scene between Ken and his son may have been Westonbirt?
