The Leisure Seeker (2018)

This is a break your heart movie about a couple who are at the end of their lives.  She is dying of metastatic cancer and he has dementia.  So if you are nowhere near this phase in your life, you definitely want to skip this because it hits all the problem notes just right.
Helen Mirren is the wife, and her life is exasperating with occasional flashes of happiness.  Her husband doesn't always even know her, much less the kids, and his well remembered threads from his life as a passionate and inspiring high school English teacher annoy her more than they entertain or reassure her.  Donald Sutherland is the mostly vacant husband who only occasionally is aware that he is not altogether there.  They cause their two offspring no end of worry when they take off in their 40 year old RV for one last adventure.  Everything that you would think could go wrong does, and even so, as it unfolds in all it's predictability, it keeps a hold on you because it rings all too true.  WIndow into many of our futures.
