I love Bill Nighy so I watched.
Wasn't a fan. 2.5*
Bening is brittle, complaining and irritating as all hell. And her accent is all over the place.
I could not feel empathy or sympathy for the narcissist the woman was. I'm surprised the marriage lasted 29 years, were I Nighy's character I'd have stopped going home to that destroyer years earlier.
I've never been a Bening fan, I find her very affected, and this didn't make me one.
