If you woke up realising the cruel deprivation of all your loved ones so that everything you treasured appealed to you as "traps", with their funerals taking place when you're still lying in a hospital bed severely battered-- how do you describe such grief? So this movie a full expression of grief, as it's title Blue" suggests.
In this indescribable numbness and physical pain, is there anyone she could turn to? Her mother whom she sought to get some consolation had nothing to offer, as she herself is a victim of senile dementia faintly pointing out that as a child she was perfectly happy. Her nana instead wept and profusely too in a dark corner. Silently she gave her a hug and asked her why? Because you don't cry was the answer. ( It's somewhat like the Heifetz, the violinist's playing, just like a tordado !! )
She chanced into a promiscuous neighbour who also went to into a number of crisis. First the residents of the building were turning her out to be saved by her last vote. And then her father came as an viewer in one of her pornographic shows, whereas she had to resort to her late husband's colleague's physical comfort.
Yes, she escaped into an estranged town, diving into the water, swimming what not. But history, or at least memories of history, was repeating itself. The street flutist played her tune and one early morning she found him sick laying by the gutter. And the mouse having begot a host of youngs in her kitchen getting right into her nerves. She didn't have the heart to dispose of them as it reminds of her own fate so much. She tried to move again but in vain. Eventually a cat has to be introduced... It was too much pain, self-inflicted or otherwise... These are all facets of her grief.
Suddenly, she realised that she was not alone in her sufferings. She was kept so far in the dark that her husband had a lover, a young and pretty lawyer, even pregnant with his baby. So, she was not the only woman whom her husband loved. Jealousy, perhaps. But out of her kindness and generosity, she gave part of her husband's estate to this future heir of her late husband. Perhaps the news came as a shock, perhaps she felt that she was no longer alone or at least not in her pain and hence her existence? But this belated straw on the camel's back came and at last made her cry ...
So her husband was an internationally acclaimed composer whom she assisted a lot. But music was duly given a low key here in the movie though in a way it spoke loud as it's so evocative. The colour blue instead reins supreme in this movie.
