The writing in the Tuesday episode was exceptional but that episode was a rare highlight of a lacklustre period in Corrie's history. I don't blame Sarah Lancashire for leaving, she was far too talented to be in it for too long.
Soon we'll be seeing a lot of dead wood characters getting killed or leaving because of the direction the new producer, Brian Park, wanted to take. Can't see the point of Joyce, Des and Andy but I thought Derek was a classic Corrie character and went too soon.
