I was like you by episode 5. I was critical of it (Ep 5 spoilers).

But after I finished the season, I changed my mind. I actually posted my own theory about it (Ep 8 spoilers) and even if just some parts of it becomes true, then I'm confident to say that the showrunners know what they are doing. That there is a some grand plan behind all of it, much like how they designed Dark's entire plot.
