I loved this series until halfway through series 4, it just wasn't the same after Sarah Lancashire left and then Peggy died. The nurses that came in series 4, Anna, Karen and Chris, their storylines were just not realistic anymore at all. You could just tell what was going to happen and a lot of the time it was really bad and embarrassing. I definitely recommend watching until mid series 4 though, proper emotion, characters you can relate to etc.
