Holocaust Survivor?

Akerman always said that Dielman was a tribute to her mother, or to "women like her mother."

Akerman's mother was a holocaust survivor. I wonder to what extent this is relevant to the film. Is Dielman meant to be a holocaust survivor? Perhaps that explains why she feels so out of time and place. Why she is maybe a little dead inside, and why she reacts so violently to her routine being upended.

If this is true, or even relevant, I don't mean to suggest that this is THE interpretation of the film, but I am surprised to not see it mentioned more often.

Anyway, put me down in the "one of the greatest films ever made" camp. I find it emotionally devastating on all counts.
