Huge Problem With This Movie
Early on in this film, the older daughter, played by a "barely there" Kate Bosworth, finds out that she has inherited her mother's condition. This means that she has a 100% chance of also developing early-onset Alzheimer's. It is GOING to happen, period.
So as she is watching her mother's decline, she is also seeing her own future unfold right in front of her. Yet, aside from the ONE scene in which she reveals her test results over the phone, this horrific and extremely dramatic situation is never again acknowledged.
Bosworth's character instead just goes on to have her IVF twins and act like a clueless ice queen, instead of dealing in any way with the fact that she is going to go through EXACTLY what her mother is going through in the not too distant future. Her kids are going to have to watch their own mother decline, just as she is doing now. (So should she even be having kids, even though they were able to assure she would not pass the condition on to them through pre-natal testing?)
The implications are huge, and it would have been a really fascinating element to explore. Instead it is just improbably dropped. If they were going to do that, they just should have had all the kids' test results come in as negative. It's just way too heavy of an issue to dismiss in a film like this one. It ruins the movie, in my opinion.
All that said, I always love Julianne Moore, and I think she did her best here, although I would have liked to see more of the "before" so we could truly get an idea of the great intellect she had before her decline. The few scenes they show us don't really convey that at all, because the decline has already begun.
