the very positive aspects of the series are around the evolution between the two main characters between betrayals and alliances, the place where the series unfolds is very claustrophobic and oppressive which puts us well in the atmosphere of a fight for life but the more negative sides are the incomprehension at times (maybe due to the subtitles of the site on which I watched it which were hard to follow at times but I think not) for example if the policeman was really in infiltration or not, the main story which is weird in certain aspects such as the fact that there is a landslide but that the "coup d'état" happens as easily as if nothing had happened and finally the third main character, the son who is there for a kidney for his father didn't really convince me.
