After watching the first episode I would say it's well done.
So far I would also say it's predictable and familiar. But I've got some - albeit limited - experience of First Nations. The town I grew up in had a large native population and unlike most white people, who ignored and denigrated them, I was fascinated by them. The boyfriend I had in high school and his friends/family had a lot of relationships with First Nations and Metis, so I gained exposure to them. In addition, I worked with an Indigenous scholar from college through to her PhD, so am very literate in terms of the Indian Act and the impact of colonialism/residential schools, etc. (the student wrote about it over and over and over again). I've also traveled through a lot of First Nations territory in my travels here in BC (one of my favorite campgrounds is on reserve land). And I was never reluctant to strike up a conversation with an indigenous person in Manitoba when the opportunity presented itself - unlike other white people in the city, who perceived a wall between themselves and the 'Indian other' (often constructed as the inferior other), or simply didn't have any interest in indigenous people.
One or more of the white people on the show had little to no experience of First Nations - one had not even ever heard of residential schools.
This show could be an eye-opener for Canadians like that, or those who are prejudiced against them.
Unfortunately, those who hold such prejudices are probably the least likely to watch a show like this, because they don't want their beliefs to be challenged. My brother is one such and I can argue with him until I'm blue in the face and present all sorts of evidence - but he is not going to change his mind.
