From NetFlix:

Anne Reid plays May, a suburban grandmother whose husband
dies unexpectedly while visiting their children in London.
When May goes there to tend to the tragic matter, she
begins to lose her grip on her identity, stripped of her
wifely duties and lost in the bustle of a world so foreign
to her. But then she meets Darren, a young man who’s
bedding her daughter, and her life takes a turn for the
complicated and the unexpected.

The New York Times magazine ran an article on Hanif Kureishi a London Indian who was awarded the Commander of the Order of the British Empire for his writing. The article suggested some of his films of which “The Mother” is the first.

I felt I had to rate this movie “Unusual and definitely not for everyone” and DEFINITELY not for children. The movie is sexually explicit. The widow loses her grip and does some embarrassing things (definite “cringe” value). I would be interested to see how severely you judge this woman if you watch the film. Wife Kathy watched the film and thought it was disturbing. I consider it a real find.

Caution!
