There are so many films with the title "Mother." Anyway, this film was enjoyable, but a total tease. It builds and builds to all these possible events as the climatic ending, and then ends with nothing.
I don't think a climatic ending would have accomplished the right thing. What dramatic incidences may or may not happen isn't important in this film ... it's the little everyday things that are harder for some than for others. The ending summed this up perfectly.
