I once read somewhere: "Aim at my ego, and I'll aim your entire existence." Yes, it's that severe of a sin. The older member of an acclaimed quartet is diagnosed with Parkinson's, and the group starts to fall apart. But this is not a movie about Beethoven's music. It's a deep character study, concerning the moment you realize, you're not as important to your closest people as you thought you were. We've all been there, and we've all crashed at the moment. I'm aghast such powerful movies fall through the cracks, and fail to attract a wider audience.
PS: This is streaming on Netflix.
