Having finished watching Squid Game, I think it is not a bad series. The story is very compact and the cinematography is quite creative. The focus on emotional content is very effective and powerful.
But to me, it suffers from the same reason why a lot of Korean movies and shows do not speak to me a lot - the characters in the show are often very unlikeable and anti-heroic. Korean shows often have lead characters that have very dark and demented qualities. This is probably due to the Korean national psyche with their very bleak and hopeless outlook in their shows, e.g Parasite, The Host, etc.
Alice in Wonderland is more in the vein of Japanese shows that tries to spin conspiracies and deeper philosophical explorations into traditional disaster film genres, e.g. Neon Genesis Evangelion, Liar Game. Sometimes these ideas or the execution are weak and ridiculous, but when they work well together, we have a great film like AIW. And in many Jippun movies, you will have positive do-gooder characters and of course the all-important Jippun chiobu.
