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.
