I have no idea how accurate this is. I do not know anyone suffering from alzheimer's and i do not know if anyone involved in this film knew or knows anyone suffering from it but i believe this film was made in good faith. Sad, sad, sad. All wonderful performances from the whole cast. Shame there was no ending. Maybe it makes sense to end it there in the fact that it makes no sense at all.
It's obviously a very commercial movie, from the cast and sad music in the background to the dialogues and the whole story (white successful couple - would a stay at home mexican mom lose any less had she had the disease? -, and then there's a mexican maid, and Kristen Stewart's role4life). I did like Julianne Moore's performance and the fact the movie gets slower along with her character's disease's progress.
