This obscure 2024 sci-fi alien show is now a big Netflix hit. Here’s why you need to watch it

It may be spring, but it’s also alien invasion season on Netflix. And while 3 Body Problem deals with that premise in a very high-concept way, it’s been unseated from the top of the list of Netflix’s most popular shows by a new South Korean series called Parasyte: The Grey.

Parasyte: The Grey is based on the popular manga by Hitoshi Iwaaki, which has previously been adapted as an anime series and two live-action movies in Japan. But you don’t need to know anything about those to enjoy Parasyte: The Grey. This is a separate story that features its own characters, and it’s clearly catching on with fans around the world. That’s why we’re sharing three reasons why you should watch Parasyte: The Grey on Netflix.

It’s the story of a girl and her alien

Fans of the original Parasyte and its previous adaptations will recognize the dynamic that exists between Jeong Su-in (Jeon So-nee) and the alien parasite that bonds with her. But for everyone else, the best frame of reference may be Marvel’s Venom. Su-in’s parasite gives her superhuman powers and she has a mind of her own.

The parasite takes the name Heidi, and the only reason why she didn’t completely take over Su-in’s body is because Su-in was badly injured and she would have died if Heidi hadn’t healed her. Because Su-in and Heidi can’t directly communicate most of the time, it makes their shared existence difficult. And it doesn’t take long before both Su-in and Heidi are forced to take sides in the emerging war between humanity and the parasites.

The alien parasites are really unsettling

Over time, you may get used to seeing the parasites emerge on this show, much in the way that the Xenomorphs became less frightening over the course of the Alien movies. But the first few times that the parasites show their true nature, it’s unnerving and borderline grotesque.

When the parasites aren’t engaged in slaughter, the show does take the time to establish what they want and how they plan to go about achieving it. That does tend to tone down how scary the parasites are, but it also gives Parasyte: The Grey a different take on traditional alien invasion stories.

It ties back into the original Parasyte

Although Parasyte: The Grey could be mistaken for a reboot of the original story, the final moments of the six-episode series make it clear that this isn’t a do-over. This is either a continuation of the original Parasyte storyline or a concurrently unfolding tale.

This final tease may not have the same impact with anyone who isn’t familiar with Parasyte and its main character, but it’s basically the equivalent of Nick Fury showing up at the end of the original Iron Man. There’s a shared universe in play, and that could lead to some exciting developments if Parasyte: The Grey gets a second season.

The best sci-fi movies on Max right now
Jack Quaid and Sophie Thatcher in Companion.

It's a good sign when Max picks up a relatively high-profile sci-fi movie like Companion, because the lineup of science fiction movies on this movie has been stagnant for months.
While it's a good thing for subscribers when Max's lineup of films is fairly consistent, it doesn't do them any favors when there are rarely new options in this particular genre. Even certain movies like Ready Player One -- which were released by Warner Bros. Pictures -- aren't always on Max. So its return is welcome, for however long that lasts. You can catch these films and the rest of the best sci-fi movies on Max below.
In need of some more streaming recommendations? We also have guides to the best new movies to stream, the best movies on Max, the best shows on Max, and what's new on HBO and Max that are worth looking through.

3 underrated Netflix shows you should watch this weekend (January 24-26)
The cast of HBO's Insecure

Netflix wants to be your television home, and it's been remarkably successful in that endeavor. The streamer features an amazing lineup of excellent shows, but when it's time to find something to watch, you might be at a bit of a loss over what to pick.
Thankfully, that's where we come in. We've pulled together a lineup of underrated series that are available on the streaming service, whether you're looking for something that will be over relatively quickly or a much longer commitment. These are three underrated shows on Netflix you should make time for this weekend.

We also have guides to the best movies on Netflix, the best movies on Hulu, the best movies on Amazon Prime Video, the best movies on Max, and the best movies on Disney+.
Insecure (2016-2021)
Insecure - Trailer - Official HBO UK
The show that justifiably became Issa Rae's calling card, Insecure chronicles a very specific slice of modern black female life. Crucially, the show is always rooted in the perspectives of its two deeply flawed central characters, Issa and Molly, both of whom deal with a variety of major and minor crises over the course of several years in their lives.
Insecure is funny, real, and remarkably open-hearted even about its more objectionable characters. Featuring an outstanding array of Black talent, the series deserved every bit of acclaim it received and its extended run on HBO.
You can watch Insecure on Netflix.
Unorthodox (2020)
UNORTHODOX Trailer (2020) Netflix
A brilliant, sensitive look at Hasidic Judaism in the United States, Unorthodox tells the story of a woman who flees from an arranged marriage in Brooklyn in order to find a new life. When the past starts to catch up, she faces hard choices about what her future should be.
Unorthodox features a stunning central performance from Shira Haas, and it's one of the best Netflix miniseries to fly entirely under the radar. It might not be focused on true crime, but Unorthodox will leave you on the edge of your seat.
You can watch Unorthodox on Netflix.
The Pacific (2010)
'Our Cause Is Just' Trailer | The Pacific | HBO Classics
A spiritual sequel to Band of Brothers, The Pacific focuses on troops stationed on the other major front of the war. This series was every bit as gripping and acclaimed as its predecessor, but it hasn't had the same staying power. Based on true accounts of Pacific soldiers, the series chronicles their journey from Guadalcanal to Iwo Jima, Okinawa, and ultimately to their return home in the aftermath of V-J Day.
Produced by Tom Hanks and Steven Spielberg, the series is a brilliant reflection of the joys and immense sorrow of being a soldier in one of the bloodiest conflicts in human history.
You can watch The Pacific on Netflix.

The cast of About a Boy.

One of the perks of Peacock is that NBC's entire 2025 TV season can be streaming for you at a moment's notice, if you don't mind waiting a week between new episodes. Although we prefer to bank up a few episodes of series like Found, so we can binge them at our leisure. That recent crime drama is one our picks for the three underrated shows on Peacock that you need to watch in January 2025.

Our other two picks include a very effective TV adaptation of a rom-com film, as well as a Peacock original series that goes to some wild places in science fiction and theology.
