I enjoyed this series for the most part, with its sly bits of humor, the complex characters and the plot depth. I am not sure what the National Treasure series is, but I know I would like to see the one with Robbie Coltrane in it. I am willing to give anything a try with Sarah Lancashire in it. She has been a favorite of mine, especially since she became able to stretch herself in various roles after leaving Coronation Street as the fan favorite Raquel. She was great in Happy Valley and Last Tango in Halifax, to name but two other roles. But back to the movie Keri. One review I read stated that even Ms. Lancashire couldn't save this mini-series, which for me begs the question, save it from what? My wife was a social worker for years, and I get tired of the disrespect that occupation often gets in movies and shows. I thought this one was more balanced than usual. She has to take her turn being disliked by the viewers, but it seems every character involved in this child's case gets that treatment. A lot of people were unsatisfied with the ending, and I can understand that feeling. I had it myself. It seems unfair. I will not give it away with specifics. I felt the writer just thought about the possible endings and thought, let's challenge them with this one. I think they chose wrong, as I don't think it is quite believable, but it didn't detract too much from my enjoyment of the mini-series
