The high ratings are understandable as it's more of a political series than a series on chess, they have literally not left any stone unturned when it comes to social justice. Feminism, inclusion of other race, anti communism, atheism over Christianity and so on, everything that is deemed cool these days. While I do support these ideals, I would just say there are better ways and works in which these ideals have been portrayed in the past. This series just came across as some sort of propaganda.

Purely from chess aspect, this show does not come across as well researched yes there are some beautiful combinations of winning a chess game, but overall it what they have shown doesn't come across as realistic, even the greatest chess players of all time have a 60% win percentage in classical chess while she literally always wins. The entire series is she playing a game and somehow winning in the end.

Moreover there are many factual inaccuracies like a guy mentioning that in a perfect game of chess white has a winning advantage because it moves first and then he mentions the same is the case in tic tac toe, that's just plain stupid both games when played optimally ends in a draw. And even beginner level board game player knows that.

If you love the political angle of this then go ahead and watch this, but if you are watching it for chess then you would be disappointed and might find few of the sequences cringeworthy. You can rather watch a documentary on Bobby Fischer on whose life this series seems to be inspired from.
