Spoiler alert:
The series starts like a crime drama mystery kind of a thing and for a few episodes we believed that. Then they added the whole time travel thing to it and in every episode they keep adding some things to it in a way which blows our mind. For every episode we'll have many questions risen and doubts and be patient everything will be answered as the series continues. I've never thought a time travel story could be taken in this way. Every time travel story is about going past killing someone preventing something but this is not like every other time travel movie. And the thing that I loved is for every concept they introduce they justify it via science. For example. The cycle 33 years was justified by saying for every thirty three years everything is aligned and it's start over again. They feed us the science behind the concept meanwhile conveying us the whole story of winden itself. It gets more and more complicated while we move towards the finale and I never thought a series with this amount of complexity could be ended with tieing all loose ends perfectly connecting all dots and it couldn't have ended more perfectly. The creators Baran boordar and jantje friese leave no stone unturned. "Everything is connected" was not just there for the sake of dialogue. The dialogues that Martha say during the play in the first season and the third season makes sense during the season finale and I could go on. Dark has set the bars high for any Sci fi series and especially a time travel series or a movie.
