Exceptional.
I almost didn't watch it because I thought it was "just chess movie." Plus I never heard of Anya Taylor-Joy before.
But I tried it out and discovered it was that and much more. If you are hesitant watch it and you will be surprised. If you are not hesitant you are correct to watch it. If you don't find it to be as great as I did, OK. Reasonable people can disagree. If you hate it, you are unreasonable.
I have seen it twice, and I am sure I will see it at least again. And I will remember Anya Taylor-Joy. She is excellent as well.
