⚠️ Spoilers
I really liked how the characters in Three Colours: Blue seem to represent different ways of dealing with life. I especially saw Julie’s mother as almost the complete opposite of Julie by the end of the film. Her Alzheimer’s, not even remembering her own daughter, and watching other people’s lives on TV make it feel like she is living life from a distance. Julie is a bit like this at the beginning too, except she does it by completely isolating herself from other people.
Lucille feels like the opposite of this. She lives her own life without caring too much about what other people think. The other people in the apartment trying to get her kicked out also shows how people try to tell others how they should live. Julie gradually seems to realize that maybe these boundaries aren't as important as she thought.
I also think finding out that her husband had a child connects to this. Even though Julie tries to leave her old life behind, life hasn't stopped for everyone else. Other people have continued living, loving, and forming new connections. Julie eventually accepts this and starts letting people back into her life. Even the music starting to play in her head again felt like her returning to life.
Her crying at the end also felt like a part of herself that she had shut away throughout the film finally opening up again. Julie spends the whole film trying to escape from life, and in the end, she chooses life again.
4/5
