I haven't seen it, and as I don't have Netflix I don't know when I would, but I'm familiar with the story.
Problem is I'm an author, and I share my WIP books at a writing group. Before Stranger Things came out I shared the early stages of a book about cloning. In them the main character is named Seven, and has blond hair, and was created in a lab. As soon as Stranger Things came out people all thought it was a fan fiction. I see the characters are similar, but not the same. But hey, maybe the two lab girls can meet up and start 7/11.
@Asriel I would support this theory, are you aware of the Steven King connected universe theory?
