Brown called on the Duffer brothers to adopt a Game of Thrones-style remorselessness when it comes to killing off characters.

Stranger Things, one of the biggest series of the past decade, has always proved unwilling to slaughter its darlings, despite its horror pretensions.
But later on, the most popular characters – Arya Stark, Tyrion Lannister – tended to make it through unscathed.
