I watched this movie in order to see how the production company will be presenting the disorder of Mutism. Upon watching all 14 episodes, it seems apparent to me that the disorder of the character of Name is Elective Mutism and not Selective Mutism. Although Elective Mutism is an outdated term, the story seemed to be based on the basic definition of Elective Mutism ("refusal to speak in 'almost all' social situations, despite normal ability to do so"). During childhood, according to the story, Name witnessed the death of his father and somehow blamed it on his mother. As a result, he refused to talk, and basically communicates via Sign Laguage and other medium, e.g. sticky notes, MSN chat. It was not clear to me, if Name refused to talk (as a choice) because of fear, or because of his rebellious behavior against his mother. In contrast, selective mutism's basic definiton is the failure to speak in specific situations and is strongly associated with social anxiety disorder.

Maybe I am missing something here, but I do welcome any Speech-Language Pathologists, who can also share his/her own thoughts about Psychogenic Mutism. My own BL Film, OSMOSIS The Series, digs deep into Selective Mutism as a result of another type of childhood trauma. Basically, I aligned it from the experience of a guest at the Oprah Winfrey Show, and therefore I presented it as a social anxiety disorder.
