We are officially living in the nostalgia era, and millennials are to blame.

Do not adjust your TV or movie screens — what's old is new again. It's official: we are living in the nostalgia era.

Off the back of iconic millennial movies The Devil Wears Prada, Bend It Like Beckham and My Best Friend's Wedding being in different stages of talks for sequels, another cherished film is copping a reboot.

Apple TV+ is developing a limited series reboot of the 2006 rom-com The Holiday, originally directed by Nancy Meyers. The series will follow the film's premise of an American woman and a British woman swapping homes over Christmas.

To add to the pile, The Social Network 2, Sister Act 3 and Princess Diaries 3 are all in the works, too. Welp.

Is anyone feeling a little exhausted by all this?

The news comes as nostalgic sequel Freakier Friday, a direct sequel to the 2003 body-swap comedy with Lindsay Lohan and Jamie Lee Curtis, is set for release. And, it follows Happy Gilmore 2, which was just released on Netflix, with Adam Sandler returning as the titular character.

Watch the trailer. Post continues after video.

The sequel saw huge streaming success, breaking Netflix records for the biggest US opening weekend. But does that mean it's, umm… good?

Look, it's not a total disaster, but one thing that has struck me about this movie — and a lot of sequels or requels (reboots/sequels) in this vein — is that they feel almost like tribute films rather than actual sequels.

Firstly, Happy Gilmore 2 puts a lot of emphasis on its celebrity cameos. And already with The Devil Wears Prada 2 — arguably the most anticipated of all these nostalgic sequels — a huge array of random celebrities have been spotted filming in New York City.

While a few of these are likely planted to confuse, it still suggests that the sequel will move in a similar direction as Happy Gilmore 2.

The onslaught of cameos makes these movies feel more akin to when a band does a reunion tour — they're singing their biggest hits, but avoiding anything new or original. And sadly, they don't sound quite the same.

Add to that the constant callbacks so often found in nostalgic sequels, and it all starts to come across as mere fan service — the characters aren't moving forward because they're continuously referring to the past.

Happy Gilmore's sequel was longer and more convoluted than the original, as if its co-writer and star Adam Sandler just wanted to add a few more circuits around the victory lap.

And in the age of nostalgia, nowhere is safe. Over on TV, we've got reboots and prequels of Legally Blonde, Buffy the Vampire Slayer, Prison Break and Scrubs on the way.

This is all despite recent failed TV revivals of millennial mainstays like Cruel Intentions, The Craft, Gossip Girl and How I Met Your Father.

And don't even get me started on the much-maligned Sex and the City reboot And Just Like That, which has finally hung up its Manolos for the last time after two movies and a spin-off series.

So what on earth is going on with this onslaught of revivals of iconic '90s and '00s movies and shows?

Obviously, it's not surprising that Hollywood is increasingly prioritising reboots and sequels. They are safer financial bets that come with built-in audiences, which also explains why book adaptations are exploding right now.

But I reckon there's more to these nostalgic reboots than just dollars and cents — and I'm blaming millennials.

(I can do this because I am a millennial.)

There's one thing that all these reboots have in common: they are deeply ingrained in millennial culture.

From the millennial quoting basically every line in The Devil Wears Prada to watching comfort films like The Holiday and My Best Friend's Wedding on repeat, or aspiring to be as smart as Elle from Legally Blonde, as loveable as Jess from Bend It Like Beckham, or as kickass as Buffy in Buffy the Vampire Slayer — these are the characters and films that shaped millennials.

And the entertainment industry knows this.

They know that all these rebooted films and shows are not mere plots, characters and scenes put to film — for millennials, they are treasured relics of their pasts.

And in increasingly trying times, millennials are craving the kind of comfort that can only be attained by diving deep into a treasure trove of nostalgia.

And naturally, whatever millennials are invested in, Gen Z will quickly follow — like millennials did with the baby boomers in the '00s, as we embraced movie revivals of TV classics like Charlie's Angels and 21 Jump Street.

But the problem is: are these reboots and sequels actually invested in furthering the story and enriching these characters, or is it all just trying to stretch out a dollar?

In the case of The Holiday series, as it stands, the original director, Nancy Meyers, is not even involved, and the original stars are not expected to return. So umm, one may wonder: what has The Holiday series got to do with the iconic classic, other than hooking millennials back in by trading on its name?

Then there are the issues with balancing fan expectations with the realities of the lives of these characters as they age. For instance, the highly anticipated reboot of Lizzie McGuire — aka a true millennial masterpiece — was cancelled due to Hilary Duff having creative differences over how the eternal teen Lizzie might navigate adulthood.

The same went for And Just Like That, with fans largely disagreeing with the direction the writers have taken the characters in their later years.

Of course, this isn't to say that a nostalgic reboot can't work. The Mummy, Ocean's Eleven, Batman Begins and A Star Is Born were all reboots and prove that, in the right hands, stories can be revived and new life and audiences can be found.

More recently, Bridget Jones: Mad About The Boy nailed the balance of paying tribute to the past while adding to the character's future with a quality story that fans can cherish alongside the original three films.

And whatever Dawson's Creek actress Katie Holmes is filming with her former on-screen and off-screen love interest Joshua Jackson, I will be the first in line to buy a ticket.

But one thing is for sure: if millennials are watching, the nostalgic shows and movies will keep on coming.
