For me the only good chapter is the first, which managed to get me hooked on the story, from the second only some episodes are good and others are very bad, and all from the beginning are unnecessarily explicit, both in the sexual aspect and in the developed violence. The original story gets lost in the tangle of characters and their stories. From the second, I found it boring, repetitive, violent and for me it became a meaningless tale in the world of the dead. It's just a ghost story with the stupid idea that the past can be changed. Summary, little by little I lost interest and stopped watching the series.
