I dislike the world building here, not because it's not interesting but because it's poorly built and explained, at least imo. All has a rather unappealing feeling of being arbitrary, since the author does not explain the world, how it works, what it's rules are and so on but rather just introduce little bits of knowledge when convenient to his storytelling. This creates, in me at least, the feeling that the author changes the setting and world at will rather than have it constructed and work on a stable foundation. I deeply dislike this.
As for the main characters, I don't like them either but I can accept them, they are pretty well defined since the beginning and their changes are slow, proper, I may not like how or why they do this or that but they make sense (except for the most important decision Reana takes, to follow Kairak, I can't make sense of that desicion, much less given when it's made and how Reana is not oblivious to the reasons that lead to that point), so I'll reserve my judgement after seeing how they develop. As for the secondary characters, since as I said above the world feels arbitrary the same goes for them, they act seemingly incoherently and the reason is sometimes explained later, this is accentuated since they all seam to have hidden agendas, again giving the feeling that the author just makes it up as it goes.
So in short, if the author really has the world defined and has the story already thought out, then the problem lies in his inability at the time of presenting it to the reader, otherwise, if he doesn't, the apparent mess of the story and chars actually makes sense.
Dropped, tried hard to end Season 1 but couldn't. Might try other time.
