How to evaluate the finale of The Story of Yunmu on the Sea in Kyushu?

I feel that the whole 75 episodes are paving the way. The details are well done, but too much attention is paid to the details. Almost every episode in the future has memories. Whether the whole viewing process is 1.5 times or twice, 1.5 times seems normal. In addition, I feel that the protagonist is not well shaped, three pairs of protagonists and three story lines can't grasp the key points, probably because the world view of the story is too great. The emotional drama is also very tangled, that is, the emotional drama of Han River and Su Yuning, which goes around again and again. One moment you tell me that I refuse you, and the other moment I tell you that you refuse me, which is worrying! And that general Muru, really. Hey. Personally, I prefer scheming, and I am also devoted to the big end, but I know how to be flexible and do things without wordiness. There is also an idiot who played 75 episodes and went back to before liberation. The whole ending is too hasty. Maybe it is a big foreshadowing. If there is a second part, I am still looking forward to it.
