A few things I noticed *spoilers*
1. I'm not 100% sure but I don't think Jacob and Anna were ever shown during sex. Obviously it was implied that they had sex, but it was more focused on the before and after and the emotional connection they shared. On the other hand, fairly intense (for a PG 13 movie) scenes showed Anna and Simon and Jacob and Samantha having sex, at the same time. I thought that was very powerful, especially when Anna's bracelet was broken and she was terrified. Kind of obvious symbolism, but I thought it was pretty powerful nonetheless. Simon breaks her bracelet and replaces her chair. Anna couldn't get over the fact that the chair was gone, even though it looked so uncomfortable to Simon.
2. Speaking of Simon, did anyone else feel like he was portrayed as controlling and sort of a jerk? I said this in another topic, too, but the way he was changing her diet and saying he was keeping an eye on her drinking was a bit ridiculous. She was obviously never unhealthy, he just seemed to feel the need to control her and change her. You can see the sadness and surprise in her mother's eyes as Simon goes on and on about it and the disappointed in her father when it's revealed she doesn't drink anymore, something they always cherished. And then the parents were clearly horrified to witness Simon proposing, which I thought was incredibly awkward for him to do that in front of her parents. It's like cornering her and guilting her into accepting so he doesn't look like a fool in front of other people. Sort of like when men propose out in public, how many times do you think women accept just to make it less embarrassing in front of other people?
3. Near the end when Anna and Jacob share a glass of whiskey, the scene is a direct parallel to one of the first scenes they shared together in the beginning of the film, except reversed. Jacob reacted to the strength of the whiskey because he hadn't been a big drinker, but he grew to love it. Anna, by the end, had stopped drinking altogether and she very noticeably winces after sipping the whiskey with Jacob, and he doesn't react at all.
There's probably a bunch more but those aspects all stuck out to me. What do you guys think?
