Firstly, I was attracted by the soundtrack of Stranger Things, which got me into watching this series. I am not sure if somebody else did the same thing as me. The music production and sound effects are so perfect, hitting my point. Concerning the narratives, I feel they lack a background story. We saw Eleven and her sister in the first three seasons. However, we somehow intuitively know there must be some psykers and how they separated. At the end of season three, I desperately want to get deep into knowing how Daddy make these work. And if there are other espers like eleven, twelve... In a nutshell, it is a ok sci-fi series with good designs.
