Maya Hawke believes Stranger Things is "extremely rare" because it is both popular and "morally good".

The 27-year-old actress - who joined the Netflix drama as Robin Buckley in season two - described the show as a "rainbow project" because it is so unlike many other programmes and she believes it has become the streaming service's third most popular show of all time because of the bonds shared between the characters.

She told Grazia magazine: "It's art, it is high quality, it is popular, and it is morally good, putting good message into the world. And for something to be popular, quality and moral is an extremely rare rainbow. And that is the highest accomplishment."

Asked why she thinks it has been so popular, she added: "For one part, I think it's the love. The love between the characters and the loyalty, and just the full commitment to each other.

"You watch that show, like I did, and you want to be a part of that group. You want to have those friends who've got your back that hard...

"It's the most beautiful thing in the world. I mean, there's nothing more special than friendship And, you know, it can be found in all places. A friendship can be developed between a mother and a son, between two lovers. It can be everywhere. I think it is one of the most important flames of love because it is the most long lasting."

Maya feels the cast got lucky because there is "genuine love behind the camera too".

She said: "We're a family and the authenticity of the loyalty among the cast and crew, [bleeds] over into the story."

The singer-and-actress - who is the daughter of Ethan Hawke and Uma Thurman - was "heartbroken" when filming came to an end and she'd jump at the chance to play Robin again.

She said: "[It was] deeply confusing. I was really feeling lost and heartbroken. I will miss it my whole life. What we all want is community, family, and like, a place to call home. And something that you know how to do.

"I don't know if I've ever cried harder than I did on the last day. If they told me I could go back and do it again, I would say yes."
