The Ken, Deirdre and Mike Baldwin storyline was one of the most memorable in Corrie's history. I can't understand why they didn't show the episode where Ken tells Deirdre to "pack her bags and go to Baldwin." Why on earth did they show the episode with Steve McDonald's wedding? Ken was barely featured. It was an awful episode.
It's probably an unpopular opinion, but
bringing in Kate Ford to play Tracy Barlow, ruined the character. One of the most dreadful storylines, was Tracy becoming pregnant with Roy Cropper's child (Steve McDonald as it turned out). This seemed to be the beginning of a rapid decline in the quality of the show.
One more observation, as much as I liked Anne Kirkbride, there was life before Deirdre Hunt/Barlow. It would have been nice to see some episodes with Ken as a younger man.
