To be honest, I am slightly appalled. Everything is pretended here: A mystery series that ultimately leaves everything open or, in a chaotic script, doesn't know where it stands at the end. The only mystery here is how such a script could be written. People who remain silent about what happened on the ship - and at the end viewers who know (almost) just as little. What is one supposed to do with that? Add to that the annoying music that sometimes almost drowns out even the dialogue, the permanent evocation of the psychological consequences of the disaster and the absolute necessity of silence about what had happened on board - and that actually happens over and over again in each of the individual episodes. Who doesn't find this annoying in the long run? 12 episodes that could have found room in a maximum of three, because everything keeps repeating and repeating and repeating ... No, I'm really annoyed.
