The show centers around Leia Forman, the daughter of Eric and Donna, as she heads to Wisconsin to spend the summer with her grandparents. Per Netflix, Leia bonds "with a new generation of Point Place kids under the watchful eye of Kitty and the stern glare of Red," and both Debra Jo Rupp and Kurtwood Smith will reprise their roles in the series as the matriarch and patriarch of the family. Laura Prepon and Topher Grace also make appearances.

'House of the Dragon' -

Fans were nervous for 'Game of Thrones' spinoffs, particularly after HBO shot and canceled a separate prequel series, but after 'House of Dragon' premiered, they breathed a sigh of relief. This dragon-filled prequel series follows the rise-and-fall tale of the Targaryen family, and it's set nearly 200 years before the events of 'GoT.' Created by George R.R. Martin and Ryan Condal, who also serves as showrunner with director Miguel Sapochnik, the prequel pays close homage to the original series, and may even right the wrongs that made the final season of 'GoT' so controversial.
