Honestly I think Kingdom so far can be split into two parts:

Part 1: Everything before the Invasion of Zhao
Part 2: Everything after

I like both, but 1 in my opinion is extremely better and has a 'masterpiece' status for me. After that, Kingdom is still decent but starts to stumble a bit in overuse of tropes, some questionable decisions, and pacing.



Story: 10/10 -> 9/10.

Art: 9/10 -> 10/10. Art is incredible and only gets better.

Character: 9/10 -> 8/10. The characters for Kingdom aren't necessarily the most deep or complex, but they are intriguing, entertaining and you'll find yourself rooting for them. There are incredible standouts as well. However, as time goes on, the cast becomes very bloated, and it becomes hard to recognize or care for new additions; also, the older additions tend to stagnate more, having their development at the beginning then staying the same for hundreds of chapters.

Enjoyment: 10/10 -> 8.5/10. I ploughed through around (I think) 450 or so chapters of Kingdom in like a week. Some of the arcs are my top in manga. The Zhao Invasion arc is when I felt the pacing slow down, a lot of weird plot decisions were made, etc. It's still a decent arc, but has a lot of hiccups. And after that I feel wary of Kingdom's future, and whether it will ever reach the heights of some of its best arcs.

Overall: 9/10. A top tier manga. After 600+ chapters it still manages to captivate me with its battles, worldbuilding and developments.
