    Did any of y'all watch The Silent Sea? It really seemed to get passed over but it was a heck of a show and deserves a second season. It was tense, intense, intriguing, and mysterious! It should've been a slam dunk youtu.be/Af_Hj0MDBBQ?...

    I’ll start. This summer I gave a talk on ecofeminism in the TV series The Silent Sea. That has inspired me to start working on a new book about South Korean science fiction film and television. It’s a whole new research thread for me, and I’m really excited for it!

    3/3 If you're not averse to subtitles, I can also recommend The Silent Sea, a K-drama set on the moon, also on Netflix. It stars Bae Doona, whom you may remember from Lost (can you believe it's been 20 years??? 20!!!) and Sense-8.

    The family finally finished THE SILENT SEA, a 2021 South Korean streaming television series starring Bae Doona, Gong Yoo and Lee Joon. We've been watching it on Sundays along with a family dinner. Overall, we liked it a lot. The cast is excellent and the production value is quite good for a series, especially the sets. IMO the story has a few of gaps & leaves open a lot of questions, but perhaps they'll make a second season. Overall, I would recommend it. #TheSilentSea #Netflix #ScienceFiction

    I have to confess I don't have the patience for a lot of American made movies because they seem so...homogenized.. Formulaic. You can guess everything that's going to happen. Most of the #scifi I've enjoyed lately has come from South Korea. One series that was amazing was THE SILENT SEA. Brilliant!

    I have started watching #TheSilentSea (Korean sci-fi drama on netflix) and am enjoying it so far. It seems to be the #DoctorWho story "The Waters of Mars," except set on the Moon, and with a background of massive water shortages back on Earth. I'm not complaining about this. The Waters of Mars was one of the better Doctor Who stories, I think, and worthy inspo. (Of course it's possible that The Silent Sea's writer has no knowledge of The Waters of Mars, and the similarities are just a…

    I also did free flow immersion (Thai audio, no subtitles). I watched the drama series about the Menendez brothers on Netflix in Thai, and watched a Korean space horror series called The Silent Sea that actually kind of slaps. I still need more vocabulary and better listening skills tho.

    Did you guys watch "The Silent Sea"? Korean show on Netflix? It's got a majorly melancholy space vibe to it. Maybe worth a look if you haven't seen it. More sci-fi than For All Mankind, for sure. But we dug that one too.

    This doesn't quite fit the question because I think the show is still good. But, The Silent Sea really falls apart in the last episode. It feels like instead of a solid ending they try to sequel bait it instead, and there is not enough there to make more. It's only 10 episode so worth watching still

    The Silent Sea is a nice sci-fi series that mixes thriller elements with mystery. The search for a mysterious sample in an isolated base on the Moon leads to a slow, deliberate progression of the story, with secrets gradually unveiled until an ending full of action and emotion.

    From a writing/ideas standpoint, the lunar seas having real water is a nice, almost poetic underpinning to the series. If you like sci-fi, I'd give The Silent Sea a watch. There are certainly worse programmes out there.

    I enjoyed 고요의 바다 (The Silent Sea), the Korean mostly-scifi series. Creative idea combining the coming desertification of Earth &desperate science (fiction). It's been done yrs now, so I'd guess no more's coming. I'm ok with that, but there are at least 2 things I'd want to know more from the ending.

    But 'The Silent Sea' works much better for a title of a spooky show! So I wonder if they decided on purpose to not do localization for that very reason. They could have chosen a different title altogether, but it's a good title! I'm so curious about it. 2/2

    Spouse and I finished watching the first season of Picard. We both love TNG. And many of the characters in this Picard show are endearing. Not the best story or script, tho. Afterwards, Spouse said, "are there any sci-fi #kdrama shows? They have better writers." LOL. So now I'm making him watch #TheSilentSea with me. As we also start watching season 2 of Picard. 😉 Any other sci-fi kdrama or #cdrama or #TaiwaneseDrama you'd recommend? #SpaceSweepers was also good.

    @AnnaAnthro I saw a few episodes of #Kingdom but couldn't really get into it. I did add #Stranger when I realized it was on Netflix. Also, #TheSilentSea which I really liked. Yes, she was fabulous in #Sense8 and it's the reason why I started following her and a few of the other actors with their future roles.

    I'd like to add the Korean show The Silent Sea that is pretty cool, Starfield for its niche nasapunk visuals and Halo 2/3 because orbital elevator are cool af and not enough considered in the genre (also, it's more logical to build a spaceship in the space than on the ground)

    3/3) Some of my favourite K-Dramas either don't involve these themes, or they do but seek to subvert them in certain ways. Would recommend Crash Landing on You and Doctor Slump. Some South Korean SciFi stuff also 10/10. The Silent Sea is great, as is a new series called When The Stars Gossip.

    Watched the first two episodes of "#TheSilentSea" on #netflix . I like it, but the story is completely unrealistic: The post-climate-change earth is a dry wasteland. Water is rationed, food is scarce, humanity struggles to survive. A spaceship survives a crash-landing on the moon after propulsion fails in orbit, then slides across the moon surface just to stop on the brink of a steep cliff. Still, the astronauts are only 8 km from their intended destination and decide to walk there. The moon…
