Though there're many aspects of this series that I give low grades, I don't think it's worth my time to scrutinize all of them here as it'll be too much, so I'll just talk a bit only about one point out of the aspect that annoys me the most which is the story. To make this genre works, outsmarting the viewers is the most important. This story already tried to do so, but it was still not wise enough, not thorough enough, not good enough. I'm not satisfied that I foresaw the answers to 3 games plus the overall plot while the characters struggled too much to find them and even intended to overlook some of them so that they could show that they had to struggle. There're a lot more to criticize about the story, but it's too messy to clarify it in a short time and I don't consider this series worth that much of my time.

I think I should also mention that I came to watch this series after watching Squid Game. They both are in the same genre broadcasting one year apart, so it's difficult to not compare them while watching. Squid Game is smarter, more unexpectant, more succinct. There's much clearer of the system design of the story's circumstance thus more convincing. The editing is more skilled. The production as a whole brings a new taste to its own genre. It's more surprising and exciting to watch. Though I'm not that satisfied with the acting of Squid Game esp. in the early episodes, when comparing to this one, Squid Game is still more impressive.
