I get what you're saying, though I can't recommend Ender's Game because your money goes to supporting gay conversion therapy. Plus, once you get into the second book, the similarities with Ender's Game becomes a lot more dubious, and by the third book disappears entirely.

However, "Opinion is all you’re going to get" and "objectively bad" is kinda oxymoronic 😉 Are there objectively bad books? God yes, I have read enough hopeful author's in my life to say that basic cause & effect or the notion of "story" as something apart from "series of events" are not always understood. However, I think you're right that this is a case of opinions based on style.

TBP (the trilogy, not just the first book) is a lot more to do with societal responsibility than a single hero (though individual failings are also a theme, though usually in how they impact society/humanity as a whole). It focuses on our place in the universe from a cultural point of view starkly different to the rugged individualism of the West (most Chinese SFF doesn't have a single protagonist), and TBP requires an enjoyment of playing with theoretical physics and geopolitics that is rather different from how they are used in contemporary Western sci-fi. So I 100% get it.

It definitely isn't for everyone, and Chinese fiction in particular can cause a lot of headaches because of this difference in how the world is perceived between Western and Eastern cultures (Legend of the Condor Heroes - another Chinese series I love - is a great example of this), so it really isn't your "fault" (I hesitate to use that word) for it not being your cup of tea!
