Remember ‘Severance’ and ‘Stranger Things’? TV Is Making Us Wait.

Time moves slowly in Middle-earth. Ages last for millenniums. Elves are immortal. Villains menace the land, are defeated, then are nearly forgotten before they re-emerge eons later.

By this measure, it has been a blink of an eye since we last saw “The Lord of the Rings: The Rings of Power” on Amazon Prime Video. But in terms of our brief mortal lives and the traditional calendar of TV, it has been a while. Galadriel and company will return for Season 2 on Thursday, nearly two years to the day since Season 1 began in 2022.

This is the Ent-like pace at which TV moves these days. The “Game of Thrones” prequel “House of the Dragon” took nearly as long to come back for its second outing. “Severance,” likewise a member of the debut class of ’22, will return in January, almost three years since we last saw it. The teen drama “Euphoria,” whose second season began in January 2022, will start shooting a third season … sometime in 2025. By the time it airs, one assumes its characters will be eligible for Social Security.

More and more, rejoining a favorite series is like trying to remember the details of high school trigonometry. Which hobbit did what to whom? What did they do all day in that “Severance” office again? Was “Stranger Things” set in the 1980s, or was it actually made then?

There are, of course, different reasons for shows to take their time returning. We had a pandemic. There were labor strikes in Hollywood. Streaming platforms have been retrenching. Individual shows can have creative or staffing issues. Ambitious productions take longer.
