Why Are We All Binge-Watching Old TV Shows? Comfort, Cost, and Culture of TV Reruns

Last Updated on April 22, 2026

Anyone who has visited this site before, or read anything I’ve ever written, knows that I love nothing more than a great whodunit.

I’m not the least bit bothered if it’s a brand-new TV show like High Potential, or one of the vast old TV shows like Poirot, Elementary, or A Touch of Frost.

The way streaming works today, I literally have my pick of what to watch. And, for those who are even mildly interested, I am currently binge-watching The Mentalist from the beginning!

So, if you’ve ever found yourself curled up on the couch, popcorn in hand, rewatching your favourite show for the umpteenth time, you’re not alone.

In fact, you’re part of a global movement that’s making old TV shows the hottest thing in streaming.

But why, with a universe of shiny new series at our fingertips, are so many of us choosing to revisit the familiar worlds of reruns?

Let’s take a look at the comfort, psychology, business, and the irresistible appeal of the cozy mystery.

Why We Hit Replay

There’s something undeniably soothing about returning to a show you already know by heart.

Psychologists say it’s not just nostalgia at play; it’s a form of emotional regulation and self-care.

When life feels unpredictable or overwhelming, our brains crave the safety of the known.

Watching an old favorite means no surprises, no emotional rollercoasters we didn’t sign up for, and no cognitive overload from trying to keep up with new plots or characters.

Rewatching a beloved series can actually help manage anxiety and stress. The predictability of familiar storylines reduces the mental effort required to process new information, giving our overworked brains a much-needed break.

It’s a way to recharge, restore self-control, and get a dose of those feel-good chemicals, dopamine included, that come with positive memories and happy endings.

And let’s not forget the nostalgia factor. Old tv shows transport us back to simpler times, whether that’s our own childhood, college days, or just a pre-pandemic world.

They remind us of who we were, who we watched them with, and what life felt like back then. It’s comfort food for the soul, minus the calories.

Reruns Rule Streaming

You might think that the streaming giants, with their bottomless budgets for new content, would have us all glued to the latest original series.

But the numbers tell a different story. According to Nielsen data, nine out of the ten most-watched streaming programs are reruns, not new releases.

Shows like NCIS, Suits, and yes, Gilmore Girls, consistently top the charts, outpacing even the biggest streaming originals.

In fact, Gilmore Girls, which ended its original run in 2007, was the ninth most-watched series across all streaming platforms in 2022, and it continues to rack up hundreds of millions of viewing hours on Netflix every year.

That’s not just impressive; it’s a testament to the enduring power of comfort TV!

Why Old Shows Win

So, what kinds of shows are we all rewatching? While nostalgia-heavy sitcoms and family dramas like Friends, The Office, and Gilmore Girls are perennial favorites, there’s another genre quietly dominating the rerun renaissance: the cozy mystery.

Cozy mysteries – think Midsomer Murders, Father Brown, or Rosemary & Thyme – offer a perfect blend of intrigue and comfort.

They’re suspenseful enough to keep you engaged, but never so dark that you are left staring at the ceiling at 2 a.m., questioning humanity.

These shows often feature charming settings, quirky characters, and a sense that, no matter how many murders happen in this quaint English village, everything will turn out all right in the end.

And let’s be honest: part of the appeal is sheer volume. Older network shows often have dozens, even hundreds, of episodes.

That means you can settle in for a long, satisfying binge without running out of content in a weekend!

Streaming Adapting to the Rerun Revolution

You might wonder how streaming platforms feel about this rerun craze. The answer? They love it.

Adding older, already-produced content to their libraries is far cheaper than developing new originals.

Producing a single episode of a new prestige drama can cost upwards of $10–25 million, while licensing the rights to an old favorite is a relative bargain.

As studios slow their output of new shows, thanks to rising costs and a crowded market, streaming services are doubling down on licensing deals for older series.

This strategy not only fills out their catalogs but also attracts subscribers who want access to their comfort shows, sometimes for years at a stretch.

It’s a win-win: viewers get what they want, and platforms keep costs manageable.

Binge-Watching Detectives at Work

If, like me, you’ve binged Elementary or The Mentalist from start to finish, you’re in good company.

Cozy mystery fans are some of the most devoted binge-watchers around. These shows offer the perfect mix of brain-teasing puzzles, lovable leads, and settings so charming you almost wish you lived there (minus the suspiciously high murder rate).

So, what should you watch next if you’re craving another cozy binge?

Here are five top picks, each guaranteed to deliver intrigue, wit, and a healthy dose of comfort:

1. Midsomer Murders

The gold standard of British cozy mysteries. Set in the picturesque (and perilous) villages of Midsomer County, each episode is a standalone puzzle with eccentric suspects and plenty of red herrings.

2. Father Brown

A kindly priest with a knack for solving crimes in the English countryside. Warm, witty, and endlessly watchable, it’s perfect for fans who like their mysteries with a side of moral philosophy.

3. Agatha Raisin

A city-dweller turned amateur sleuth brings humor and style to the Cotswolds. The mysteries are light, the characters are quirky, and the setting is pure cozy escapism.

4. Shakespeare & Hathaway: Private Investigators

An odd-couple detective duo solves crimes in Stratford-upon-Avon. Expect Shakespearean references, plenty of banter, and mysteries that never get too dark.

And, don’t forget that a fifth season is in production and should be with us later in 2025.

5. Rosemary & Thyme

Two gardeners-turned-detectives solve crimes in some of England’s most beautiful gardens. It’s as much about the scenery and friendship as the mysteries themselves.

Honorable mentions: Miss Fisher’s Murder Mysteries, Queens of Mystery, New Tricks, and Death in Paradise – all beloved by cozy fans for their charm, wit, and binge-worthiness.

The Bottom Line: Why We’ll Keep Coming Back

In a world that feels busier and more unpredictable than ever, the comfort of a familiar TV show is hard to beat.

Whether you’re seeking nostalgia, a sense of control, or just a way to unwind without surprises, reruns offer a safe haven.

Streaming services are happy to oblige, filling their libraries with the classics we crave, and saving a bundle in the process.

So the next time you find yourself rewatching Morse, solving crimes with Patrick Jane, or sipping tea with Miss Marple, know that you’re part of a global club of comfort-seekers.

And if anyone asks why you’re watching that old show again, just tell them: it’s good for the soul – and the streaming charts agree.

Now, pass the popcorn and the remote. The next episode is about to start.
