I found myself changing my opinion on characters multiple times while reading. Feel like at some point, it's less about which determining which characters are explicitly "right" or "wrong," as there are consistent reminders that point out "why" a character might have developed or behaved in certain ways. Of course this argument only extends so far and shouldn't be used to justify really shitty behavior, but for the most part, all the characters undergo what what can commonly be described as typical human struggle - touching on romance, death, personal direction, etc, but done in a manner that feels convincing. There's a wide cast of characters, each with their worldviews that attempt to shine line on the events that unfold, which adds interesting perspectives.
Admittedly some of the developments / events feel a bit forced, more apparent for the sake of plot progression and such, but they still serve their function of presenting interesting "what would you do" situations involving relationships, responsibility, obligations, etc.
The art can be really gorgeous, especially the cover art / "eye catch" illustrations at the start of volumes and chapters. Some of the ones in the later chapters are really striking, no doubt as a result of the author and reader having stuck through all the character development (15 years of serialization). Think these illustrations also made me think more about still life(?) paintings of people and portrait photography.
