Stunning performance by Colman and Hopkins. The first part really left me confused and suspicious on what's really going on. I was clueless, bothered and tired of wondering.
But it all made sense later. And what became apparent to me in the end, is that for about one and a half hours, I experienced having dementia. And it was awfully confusing and heartbreaking-- to live everyday with an unresting trouble for clarity, which we all abundantly enjoy and probably taking for granted while we are young.
With the chance to be equally demented and feel the horrible experience that was, compassion grew in me. And so as what the character of Olivia Colman represented-- that, I think, the very purpose in the film was to be a final note for everyone to give compassion, patience and maintain respect to our elderly. What they're going through is unimaginably hard and to make it worse, they don't even know why.
Their remaining years is just our one and a half hours. We've felt and learned so much how to be them in that very short time. Now it's impossible to go out there and not see the struggles and share compassion with those on the final years of their lives.
