I'm at 4th episode, super curious how the whole story ends. I think Anya Taylor-Joy is a lot of joy in fact, simply brilliant, but it's only my opinion. The actress who plays Harmon in episode 1 (circa 10 yo) - not so much, I can't even be bothered to check her actual name. Too stiff, acts like a robot.
The aesthetics of the series reminds me the French movie Amelia, but without the humoristic part. Does anyone remember it?
Also a little Polish accent, the Russian chess master is played by famous Polish actor Dorocinski.
