El Eternauta (2025)

I'll get right to it: this is one of the best shows of the year, and one of the best Argentine shows of all time.
What I'm saying is obviously premature, given that at the time of writing, there is only one season, which ends on a cliffhanger (MY GOD, what a cliffhanger!!)
The show begins with a regular summer night in Buenos Aires, Argentina (it's December because we're in the Southern Hemisphere). In the middle of Christmas preparations, end of the year plans, street protests, and regular hangouts with friends, snow begins to fall... snow that kills you instantly on contact falls from the sky without warning. The only ones who survive are those who just so happen to be sheltered from it.
More stuff happens after that, but you'll have to see that for yourself.
So, beyond the danger of the outside, the overwhelming ocean of death and despair, you also have to watch out for anyone who did survive, as society no longer is... or is it?
Without getting into too much detail, there's a lot of human organization happening in this show. People attempt to make something together in order to just... live, and what they make is shaped by the kinds of relationships they had with their fellow human beings to begin with. The post-apocalypse isn't a blank slate, it's made from the pieces of what was before.
Of couse, that's not the only thing that happens in it. The main character, Juan Salvo, excellently played by Ricardo Darín, also has his own goals and demons... and some of the things that happen are clear if you read the comic.

Speaking of the comic, the two works are quite different. A lot of the themes are the same or very similar current-day versions of them, and there are a lot of recognizable elements, but the show is clearly going in another direction. The characters in the show are more realistic (which isn't a flaw that the original comic had, it had more comic-book-like characterizations, which was pretty appropriate for that medium), and the human aspect to that incredibe tragedy is much more palpable in the show.
In the comic, it takes the characters almost no time to pick up arms and fight with a soldier-like discipline, which isn't bad! It works for a comic book, where explicit description carries a lot more weight than lifelike character moments.
Whether you've watched the show or not, I highly recommend reading the comic, the story is fantastic, and you can FEEL its very specific Argentine point of view. Stories based in the fears of the Cold War are often told from the perspective of what was called the First World, the US aligned countries. The Eternaut comes from the position of a non-aligned nation in the Global South. As such, there is a great deal of powerlessness in the comic; your foe is so far above you in terms of technology, skill, organisation and ruthless dedication that it does not even see you as an enemy but as a resource to be conquered and exploited.
Speaking of the unique perspective of The Eternaut, that's another great aspect of both the show and the comic : The setting of Argentina. This is not the United States: there's a shitload of Argentine music in the show, the characters play Truco, guns are not common and few people know how to use them, a lot of old technology is still lying around, and Juan (in the show) is a veteran of the 1982 Malivans/Falklands War. For Argentinians (well, the ones from Buenos Aires), it's also surreal to see so many recognizable places in a sci-fi apocalypse setting, which typically shows US cities. I can't count the amount of times I screamed "I'VE BEEN THERE!!" at the screen suring a scene. If you haven't been to Buenos Aires, you might not get anything out of that, but it's a neat thing :3
There's a lot I'm deliberately not talking about, because I really want you to watch it and read it.
As of the time of writing, the show is on Netflix with great English subtitles (but a pretty lousy English dub), and the comic has been officially translated to English. I do not know where to buy the comic in English, but there are... places where you can find it online.
If the second season comes out and it's dogshit, I will retract my recommendation. For now, it's a supremely good show. The comic is also excellent, read that as well if you want a very different take on classic sci-fi.
Nobody survives alone.
