This show is extremely complicated. it seemed like stranger things in first episode but it's not, I personally feel stranger things was far better and actually made sense. In dark, I don't understand in what sense a person is in past and is aging in past at a normal speed, then also is present in his present and also simultaneously changing the future. how is that even possible? A person dies in the first episode before he actually vanishes into the Cave. It's about time travel which is very mind confusing🙁
