The Father (2020)
I gave this film a wide berth for a while as I had been caring for my dad with dementia for a couple of years around that time. Everything about it is well-executed. I wonder if it might be a good primer for family members not knowing what to expect when someone close gets dementia, partly because I felt it conveyed well the confusion the person with the condition experiences. I've wondered if having dementia is like waking from a traumatising dream, half-remembered tendrils of untruth from the dream warping one's point of view, and the act of trying to find your feet with reality again, just all day long.
Emotionally, it was hard work. Not a film I'll be coming back to, but if you enjoy decent actors hitting performances out of the park without all the usual hollywood drama, you might want to check it out.
