Fantastic show with a strong narrative structure and organic character development.
The first season does an excellent job of establishing characters and the base story for the series, it feels slow at first but theres a sense of building throughout that brings you to a finale that is a rush of emotion and narrative intrigue.
The second season does much the same but ups the game somewhat, introducing characters (one in particular who is an on point parallel of the Zuckerberg style tech mogul) and extending the narratives into new and interesting areas. The difference here is that ethically "Humans" begins to ask some big questions and question not just the beliefs of its characters but its audience too. The finale here is poignant and stark but leads into the third and final season in a spellbinding climax.
The third series takes everything from the previous two and brings the story arcs of each of the main characters into an even sharper focus on a larger and more dramatic scale than before. There is heartbreak, heartwarming moments and a worrying truth to the narrative that keep you invested and tie you to the characters in a truly unique emotional fashion.
A fantastic show that could have gone on for much longer, but like many has been left short and sweet. Recommended!
