If you like the French \ European series Into the Night, in which the passengers of an airplane flee the deadly luminosity of the sun. This series is worth watching.
Same apocalyptic premise, let's say basically the same universe, different main language, a submarine instead of a plane, human beings trying to survive an impossible situation.
I loved the first season of Into the Night. The second one more or less. And I think this series will be more on par with the second season of the series I mentioned above. Maybe a little better. I saw the entire series in one sitting. I liked the characters and the atmosphere.
And even though this series isn't perfect, I think it's very edible.
But please, check with the original audio, the main language is Turkish, but there is a lot of conversation in English, Greek, Italian etc. I think the dubbed version ruins the experience a little.
A 7 out of 10 for me.
