there's obviously the whole culture and fandom and the ways people characterise the characters themselves, which is a whole other matter (gotta stan KAITO, what a dork) but even just from a music perspective, i've been listening to so much of it again lately (my thirteen year old self would be delighted to hear it) and people are so creative i love it! there are so many really talented producers and project sekai has been somewhat of a gateway into me finding new ones (like the producer r-906 and the song heat abnormal) :)
