You're perfectly welcome to do that, but it still has no relevance to my opinion that a fan of the Gran Turismo series would enjoy watching this documentary.
And now, we get to the heart of the issue - you're afraid that a positive celebration of Kazunori and the Gran Turismo series will prevent the changes you'd like to see in the games.
The problem with that perspective is that it's rooted in egocentrism: "I don't like it, and you're not going to like it, either!" (This works in both directions, by the way.) It's not a constructive way to debate the merits or problems of something, and will typically only produce an argument - although the cynic in me suspects that's often the only intended outcome...
Regardless of what you think about Kazunori or the Gran Turismo series, he was the first person to overcome the mountain of technical, political, legal, logistical, and marketing challenges which stand in the way of producing a driving simulator, and he was the first to do it it in a way that generated wide, mass-market appeal. Meanwhile, he's created thousands of jobs for people (including all of the competing development shops and accessory manufacturers who are working on products in a niche legitimized by Gran Turismo), influenced the automotive and video gaming industries in a significant and positive way, and has provided countless hours of enjoyment and entertainment for tens of millions of people who have played his games. Whether you like it or not, that's something I will continue to celebrate and respect.
