I gotta say, when Humans debuted,i found it interesting,well acted but nowhere near as deep,powerful,intense and provocative as the show it has evolved into at season 3s end..this is some seriously powerful,moving stuff here! I love these types of shows, such as humans ,battlestar galactica.Caprica , that depict the awakening of machines to consciousness and the revolt that is inevitable when those who were enslaved and made to serve begin to assert their desire of freedom and equality..the storylines with Mia and Niska are fantastic, to see what they have become and the transformational wave that has been initiated by them...This series has gone from interesting, to Very Intense, mindblowing and disturbing in its ascent to season 3...i love it and hope there is a season 4, the stage has certainly been set for its continuation..
