It's been nearly six years since Lost came to an end. SIX YEARS. That's the length of time that Lost ran in the first place.

And we all know that six years is plenty of time for nostalgia to blossom into a huge forest. An island, maybe.

So, could Lost actually return in some form in the future? Let's look at the evidence thus far.

1. Lost had a pretty definitive ending

The main obstacle in the way of a Lost revival is how the show ended. 'The End' saw all the main characters reunite in an afterlife-type place, long after every one of them had died – whether their demise came on the island or many years after escaping it.

This makes the idea of some or all of the main characters returning kinda pointless. Yes, in the world of timey-wimey sci-fi nonsense, they could get explain away the whole 'flash-sideways', but it would piss off a load of fans.

We can only think of two ways it could work - one would involve doing Rogue One-style stories that took place after Jack died on the island, but before everyone else did. We've always loved the idea of finding out what happened when Ben and Hurley ran the island with Walt (if you haven't seen the bonus DVD scene that brought back Michael's kid, watch it now!).

Either that, or they would have to create a spin-off series that took place in the same universe, but with entirely different characters. But would anyone really want to see that? We doubt it.

2. What do the main writers think?

Co-creator and showrunner Damon Lindelof revealed in early 2017 that he would welcome any pitches for a Lost revival, but said that he probably won't ever go back to the island.

"Those characters not only died, but we showed you their experience post-death," he told Entertainment Weekly. "Any new take on Lost will probably have to feature new characters, as it should."

And Lindelof also feels that it's not his place to return to that world himself, and that someone else should do a revival... if it it happens.

"As it relates to Lost, which was so heavily serialised, I do think it's somewhat of a betrayal to go back in and say there's more story to tell that I just came up with now, especially when we had ample time to end it on our own terms," he explained.

"[Co-showrunner] Carlton [Cuse] and I always said that we welcome any future crack at the [intellectual property]. Lost was bigger than us and bigger than [co-creator] JJ [Abrams].

"There's something really exciting about the fact that George Lucas sold the Star Wars universe and now the people who grew up watching it are making it. Maybe the same thing could be said for Lost."

Meanwhile, Carlton Cuse told Digital Spy in 2014 that he wouldn't be surprised to see Lost return in some form eventually.

"Disney owns the franchise, it made them a lot of money, it's hard to imagine it will just sit there idly forever," he said.

"Damon [Lindelof] and I told our story in that world and I assume someone will come along, hopefully having been inspired by our story, or our version of the story, and want to tell their own story.

"It's like the Narnia chronicles. There are seven books, they were all written by CS Lewis, but they all visit Narnia at different times and different configurations and different ways.

"Someone is going to come up with a way to tell another Lost story. I think it's inevitable. I don't know what it is or how it would work, but I can't imagine something else won't be done with the franchise."

3. Everything else is being revived

We live in an age of countless Hollywood reboots and remakes, and now TV is getting in on the act.

In recent years, we've seen these cult shows getting some form of a revival:

So, why not Lost? It fits into the bracket of the type of geeky show that fans still hold dear. However, these revivals have had mixed receptions since coming back. Heroes Reborn was slammed to the ground, the new 24: Legacy without Kiefer Sutherland's Jack Bauer is questionable, and the jury is still out on Prison Break.

4. Most of the cast are available

Aside from Evangeline Lily (Kate), who's been bossing it in the Hobbit and Marvel movies lately, the majority of the other cast members could probably do with a Lost reunion.

For example, Josh Holloway (Sawyer) and Emilie de Ravin (Claire) have kept busy in various TV shows, but none that rival Lost in the ratings and popularity stakes.

And then there's stars like Matthew Fox (Jack), Terry O'Quinn (Locke) and Jorge Garcia (Hurley), who haven't had anything close to a big hit on Lost's scale since leaving the island.

While they might not be able to round up every single one of the Losties, there's a big chance that they can convince a large chunk of them. But would they want to?

5. There have been mini-reunions here and there...

In 2014, Cuse and Lindelof reunited along with some of the main cast for a 10-year anniversary event:

So, that shows that the majority of the cast are on good terms and would probably enjoy some kind of reunion – but maybe only if Cuse and Lindelof were in charge.
