I've loved every single episode of this show. The casting is second to none and Nicola Walker is breathtaking as Hannah Stern. The dynamic between the characters works on every level. It's a sensitive and difficult subject and you get to see all aspects of that across the series. The writer/writers got it spot on. Easily one of the best U. K. drama shows. It is an emotional roller coaster, heartwarming and sad. There are predictable elements that shock when it happens and then others you second guess and are left strangely disappointed that they didn't happen. Thoroughly engaging.
