The Silenced, or the title literally translated as "The Lost Girls" have all setups you want to see in a mystery boarding school/orphanage movies. It includes mysterious rules, secret room, long dark halls, and confused school girls. This movie set in Japanese occupation era in Korea, where an all-girls sanatorium/boarding school to prepare them to go to Tokyo for a scholarship while recovering their physical health. But, little did a sickly girl who are new in the house, students are missing one by one.
While all seems perfect and I am ready to love this, I encounter myself in a confusing situation where I can't differentiate all of the students' faces. They wear uniform, they share same hairstyle, quite same body type, and I am trying enough to focus on their facial features to determine who's who and I give up and only knows who is she after her name is mentioned. Although this is very subjective and minor to the whole movie, I feel this situation withdraw me to join the buildups to the climax. But ... only if the buildups are good.
Another problem is, I think the movie is too dragging to explain or showing something. It's good at first because we have some bases to know what you may expect in terms of gore/jumpscares/violence you may encounter in the movie, but some depictions (like the main character having treatment in bed) happens for at least five times without any major development. It makes me difficult to follow the narration and to build the anticipation to the climax.
When the climax is happening, I was quite entertained, but it's too stale after watching many buildups, so it just felt flat. I like it more if the buildups can be more focused on one theme and cut the drama scenes. With lots of conflicts without any sort of increasing tension (and I don't know who's who), it seems that the climax (with quite obvious resolution) can't justify the movie as something worth watching, compared to movies with similar themes.
Even though it's quite low in my perspective, for those who like some glimpses about what's happening in Japanese occupation (although it's probably not quite accurate either), you'll like this one. I, for instance, like how they used Korean and Japanese language interchangeably in the movie to depict what is the status of the language in that era. More than that, I guess you can have yourself a try if you like this kind of movie, but I'm sure it's easy to find another movie that have better buildups, and you can differentiate the actors' faces.
