Julie has had great potential but the writers like a few others have let her down. She came in as a potential girlfriend to Kirk like a few others but it didn't last. They realised she had potential, and kept her on. The Eileen/Paula/Julie/Colin story was fantastic and really well done. It was quite powerful and character driven.
But since then its all been a bit messy. Her and Brian were a great couple. And the miscarriage story was beautifully told. And it was nice to see them set up home together. But getting rid of him was a mistake, as was the way they wrote Julie during the Kirsty story. Julie had known Fiz a long time and she was her first friend on the street and she just turned on her? Unbelievable. Now that Brian has gone, Julie barely interacts with the Grimshaws and has little solid connections.
Lets see more Eileen and Julie, reunite her and Brian, give her a pet to fill her nurturing side and give her some solid friendships. I think a wee friendship group of Julie, Anna and Mary might be quite lovely to watch.
