‘Stranger Things’ Season 5 is ‘ruined’ for new star Linda Hamilton: ‘I won’t be watching’

Seasoned actors also have second thoughts — even if they’re cast on a hit series.

Just ask Linda Hamilton.

Hamilton, 67, said she had “imposter syndrome” after joining the cast of global phenomenon “Stranger Things,” which is ending its trailblazing run on Netflix with its upcoming fifth and final season.

“I’ve watched it every season with relish. I just love it,” Hamilton told Us Weekly. “So it’s kind of like imposter syndrome where I don’t [feel that I] fit in there.

“That’s a whole world set in the ’80s.”

Still, Hamilton said that because she’s such a fan of the series that made it even harder to accept that she was now part of the cast.

“When you really buy into something, you don’t see yourself in it,” she said. “So I think in a way, it kind of ruined the show for me.”

Hamilton, who stars in Syfy’s “Resident Alien” as Gen. Eleanor McCallister, was mum on details about her “Stranger Things” character, as is Netflix.

“I Zoomed [series creators] Ross and Matt Duffer, and they gave me the shape of the character, but not of the story,” she told Us. “Because they have to be very careful with their story. So I still don’t know how it ends. And it takes a lot of discipline to not know where it’s going to go.

“But that’s to protect it from all of the people that want to know.

“I don’t share, but I’m having a really good time,” Hamilton added. “I have friends now that will text me and go, ‘Where are you? Or you can’t say?’ But that’s out of respect and love for the Duffer brothers.”

But while she might have felt imposter syndrome joining the “Stranger Things” universe, Hamilton said she’s really enjoyed the experience.

“I’m thrilled to be part of it. But I just never, ever saw that one coming,” she said. “It is different when you’re a fan of the show to sort of go, ‘Well, how do I fit?’ But we’re working on it.”

She also said that she won’t watch the fifth and final season. “I never watch [a project] once I’m in something,” she told the outlet. “It would just completely take me out of the reality of it to see myself in there.

“So I won’t be watching.”

Season 4 of “Stranger Things” concluded with Eleven (Millie Bobby Brown) escaping from the military’s attempt to kill her — and from the clutches of evil Dr. Martin Brenner (Matthew Modine).

Meanwhile, the other characters battled Vecna (Jamie Campbell Bower), while Eddie (Joseph Quinn) lost his life pursuing and defeating the Demobats.

And there was another death (well, sort of): Max (Sadie Sink), who died during the battle with Vecna, was brought back to life by Eleven, although she was in a coma with no word on whether she will recover.

As all that was transpiring, Hopper (David Harbour) and Joyce (Winona Ryder) sealed their love with a kiss after she rescued him from a Russian prison camp. They returned to Hawkins. but their bliss did not lost long as particles from the Upside Down rained down from the sky and destroyed the grass and flowers — as the final shot of Season 4 showed the sky filled with red lightning.
