Pugh has a few solid scenes as the older Amy, but her playing the younger version was just too much of a stretch and the non-linear jumping doesn't help.
On the flip side, I really liked what they did with Beth. There was a real effort to illustrate her and give her some strength and desire of her own. You could see how she and Mr. Laurence bonded. And although she's clearly sensitive, you don't get the vibe that Beth is a total pushover compared to her sisters. Claire Danes' version looked like she would blow away, and I say that as someone who loved that film.
I also appreciated what they did with Meg, and how they showed her and Mr. Brooks together. And honestly, I thought Emma Watson's accent would be a lot worse than it was.
I get the significance of the scene with the publisher near the end, but the rom-com vibe of it was just silly and cringeworthy. They could have kept that whole five minutes.
Not having read the book, I always thought that Jo really refused Laurie because she didn't love him romantically, not just because they would be a bad fit. But this time, I felt bad that Jo was actually reconsidering his proposal because she was lonely and could envision herself married to him. You could understand that feeling of being lonely and wanting your independence at the same time.
Performance-wise, Dern and Chalamet were miscast. Ronan was great as usual, the others were fine. Scanlen deserved more props than she got.
As a movie, it's not bad, but I don't need to see it again. It's about 2.5 hours and it felt long. And like a few people mentioned, the movie doesn't hit the emotional core the way it should.
