What's the problem here?

I thought about it for a long time, why this show is not as good as it could be.
I personally have no problem with actors. (I wouldn't watch a series just for their sake, but I think they did a decent job.) The story is interesting, so I keep watching, but somehow I still don't really enjoy it.
(I also read the novel, to see if I can figure out what's wrong with the series. The novel is adapted almost one-for-one. So the fault is not to be found in the series)
The problem, I think, is that the political and military thread should be the main thread, and the love thread should be a secondary thread. Here, however, the focus is on the love thread. In this case, the writer subordinated the action to the bickering of the main characters. And it's boring, drawn out and pointless in many parts.
A literal adaptation of this story is a mistake. In 2024, this is already the 3rd Chinese series that either should not have been made into a film, or the original idea should have been reworked into something faster and more spectacular.
