Stranger Things star Gaten Matarazzo has spoken out about his “fear” over the impending end of Netflix‘s hit series and what it might mean for his career.Speaking on The Tonight Show with Jimmy Fallon on Monday (March 20), Matarazzo – who plays Dustin Henderson in Stranger Things – said when asked how he felt about its upcoming final season: “I mean, it’s something that’s so important to all of us and has just been essential to the growth that I’ve had over all of my teenage years into my 20s. It’s the defining aspect of the past 10 years of my life, practically the past decade.”Matarazzo added: “There’s kind of an excitement there because you always want to wrap it up and you want to see how these characters are going to finally develop one last time, and how they’re going to finish their journeys. But also there’s like a deep fear.
