    I have seen worse...

    It's a story that doesn't really tell anything new. The show is nevertheless quite entertaining and in places really exciting. However, the story is not quite convincing, especially since there are some rough plot-holes and logic errors, and the ending is not really satisfying either. Some effects and also the set can't always convince. But since it was not a boring story, I can give 6 stars.

    Decent sci-fi show & a new experience in S. Korean filmmaking

    I am not a fan of sci-fi or space drama/thrillers but as a fan of S. Korean movies and TV series, I gave it a watch. Overall, it's slow-burning with a somber mood, different from other sci-fis of this kind giving out a realistic feel of their challenges, no aliens or creatures about but something more mysterious and deadly, with intriguing twist and turns and you have to watch all the episodes patiently to really experience the show. There is also a very important message - climate change and the effects on future generations like water shortages which can easily happen if not already. Some of the acting surprisingly was not up to par for me but maybe because this whole project was a complete new experience for all involved. I think, the show would have been better with fewer episodes but for a new director and first attempts at this kind of genre, I was really impressed and enjoyed the show.

    However, I like to point out somethings based on the comments/reviews I have seen a lot lately (Squid Game, Hellbound, My Name, etc.):

    1) There is so much comparing every recent S. Korean show that comes out to Squid Game. Even the reputable sites that review films/TV shows are doing it. It's ludicrous and at this point aggravating as if all recent S. Korean shows must somehow be like Squid Game to be worthy or that's all they have to offer!

    2) I have seen some reviews that seem suspicious and generic whether rated high or low. Sadly, I have even seen few racist ones!! Not sure even any of these ratings were based on actually watching the shows??

    3) There is always some comparing the shows from other countries to Hollywood ones as if that is the "ultimate standard". International shows have become very popular in recent years so they must be doing something right. Viewers these days, at least some, are looking for something really original, unpredictable and emotionally engaging and with natural acting and great character build up/storytelling (fast or slow-burning) which is offered more in international films and TV series than the Hollywood productions. You can find reviews/comments to that effect as well.

    Anyways, I definitely recommend watching this show because it has a new approach to this type of genre. South Korean filmmaking can be very innovative and this too does not lack in some originality,

    Kept me edge of the seat whole time

    I don't care about bad reviews. All I know, I loved it. I watched it within a day. People are claiming it doesn't make sense but a fictional drama doesn't need to make sense, I guess :3 I thought, I would watch the next episodes in next day as I started watching it 7pm but I watched it till it ends. I regret why I watch it! Now I have to wait til the next season comes ://

    Watchable but it ignores logic too much.

    A well paced space drama with lost of challenges for the characters. There were a few items in this that were immensely illogical which makes you wonder if the writers know much about science?

    For example they have the characters walking in slow motion whenever they're out in the vacuum. Well, this is plain silly and doesn't happen in reality. Just look at real moon-walking footage. Where is the resistance in a vacuum?

    And taking off their helmets in a facility where they know there could be undetectable bio-hazards, where the staff previously died of unknown causes and before they have checked the air for hazards. Much like the similar ridiculous scene in Prometheus where so called 'scientists' remove their helmets in a building on a new alien planet after they just arrived.

    Apart from this the main story in quite fine. Do hire a science advisor in the future though :)

    Good Enough

    Korean Drama "The Silent Sea" is a decent attempt to create a post-apocalyptic drama with loads of suspense and thriller factors.

    And for sure, the drama keeps things edgy and suspenseful till the very last minute. The viewer is thrown straight away into the action, with the earth struggling to find water to support the needs of the population, and a scientist is forced to leave the planet. And there is a nudging feeling that something is off right up when the team lands on the moon and goes into the base. That feeling is maintained all throughout the story. In addition, the mystery that is formed and solved is well constructed, well presented, and perfectly paced. It gives small cheese bites throughout the episodes, and it concludes everything nicely in the final one.

    However, the drama leaves a lot of things out. The condition of the earth and the dystopian current situation is not well explained and just given as a fact rather than something that needs more exploration. The characters are also the losers of the mystery-thriller focused story. There are some flashbacks that indicate some short of past and personalities, but other than those, the characters are left as blank ones that were acting on based on their initial introductions. The CGI, moreover, were bad and almost ruined the atmosphere of the drama at times.

    On the other hand, the performances were top notch, as expected by top tier actors and actresses.

    So, overall, 7.5 out of 10.

    • Trivia
      It is the first SF space drama to be attempted in Korea.
    • Goofs
      While outside on the surface of the moon, the astronauts are walking in slow motion. Yet the moon has much lower gravity than Earth and far less atmosphere, so they would be able to stride and jump much more rapidly than on Earth. Also, inside the lunar base they go back to moving normally while wearing their space suits, even the gravity would be the same.
