Terrifying space series is being called one of the most underrated on Netflix

Netflix users are still raving about a space series two years after its release... meaning it must be pretty damn good.

The Korean-language series dropped on Netflix in December 2021 and, despite its popularity, hasn't had a second season yet.

But that could all change soon as there's rumors of more episodes could eventually be in the works.

Titled The Silent Sea, the eight-episode-long series boasts an 80 percent score on Rotten Tomatoes' Tomatometer.

The synopsis reads: "During a perilous 24-hour mission on the moon, space explorers try to retrieve samples from an abandoned research facility steeped in classified secrets.

The Silent Sea stars Gong Yoo and Heo Sung-tae, both best known for starring in Squid Game, as well as Sense8 star, Bae Doona.

In recent days, someone took to Netflix Bangers to ask people their thoughts on the two-year-old show, and as quickly met with rave reviews.

"Loved it!!" one person said, while another added: "The only great series I can remember."

A third went on: "It was stunning," while someone else hailed it as 'worth watching'.

Others expressed their disappointment that a second series hasn't been confirmed.

"It was very good. The only bummer was there is no second season for this," a The Silent Sea fan penned.

"I liked it a lot. It’s a solid sci-fi with a fantastic lead cast in Bae Doona and Gong Yoo," continued another.

"The supporting cast are great the effects etc. are very good. I was hoping it would get a 2nd season though."

But this may change as it's been noted that Netflix referred to the show as 'season one' rather than a 'limited series', meaning a second season could still happen.

The streamer also hasn't officially announced that it's been cancelled.

Upon it's 2021 debut, Squid Games' Gong Yoo expressed his hopes that The Silent Sea would 'open the door for potential development'.

"I think that this is a meaningful first step for the specifically Korean space sci-fi genre," he told Sports Chosun.

"Personally, there are parts that I'm very satisfied with, and I think it was brilliant for a first step.

"Many people watch from different perspectives, but I think of those diverse perspectives as garnering more interest in the drama, so I'm grateful."

The Silent Sea is currently available to stream on Netflix.
