This beautiful tale of a woman Elise coming to terms of accepting the disappearance of her sister Frances is one of those movies that you will never understand if you don't listen to the dialogues attentively, which makes the movie even more interesting because there is no clear cue as to what really happened to the character whom the central emotions of desperation, longing, melancholy and even confusion revolve around.
The way the movie presents its conflict is flashback. Flashback is a great tool to present two realities that are quite complex. In this movie it is used effectively through the aid of great cinematography. There are moments when flashbacks are too lengthy to be useful to the message the film tries to convey but overall, it was used in a palatable manner.
One problem I find the movie is characterisation. There are characters that are confusing as to how they are related to the one another because the characters themselves are off-tangent and exaggerated but acted in a restrained and underwhelming manner. Especially The doctor, Elise's love interest.
Overall, the film is beautiful. Quite dark but beautiful. If you pick up the cues, you'd probably know more than Elise as she seems too oblivious of the fact that her sister was giving her signs that something wasn't going well with her life that possibly led to her disappearance. In the movie the resolution is as unclear as the the conflict but true to what the film is suggesting that in grieving and moving on, you do not need to know all the intricate details, you just need to do it to better yourself.
