the ending
I felt the ending was very forced and rushed, but that might have been intentional on the part of the filmmaker. The film is basically a snapshot of Aimie's life over a period of about two weeks (I interperted every time she
talks to her father and we see the landscape as the passage of a day, hence the title), so we know very little about her life before or after the time shown in the movie.
Furthermore, all kinds of stuff could be occuring offscreen that we don't even see. What's her real relationship with Steve? Does she have friends besides Tran? Is she actually sending letters to her father or just imagining that she's talking to him? When her mom says that the dad walked out on the family, what exactly does this mean? Is her father even still alive?
It would seem that Aimie and Tran meet new people, form relationships with them and drift apart, but can we be sure? I interperted it as their assimilation into North American culture; thus they don't feel they need each other anymore.
I'm actually not sure, just because the film gives no real indication of where she's headed after the film cuts off.
