I fit the age bracket above and personally i think DC is awesome. I bet personal likings play a big part. ON my part, I really enjoy thrills and mysteries and like them even more in DC. It is also fun watching the anime transition of graphics from year to year.
Characters- cute, smart, witful and cool personality
Plot- interesting and mind bugging
Graphics- really cool
OP, ED and others are enjoyable.
and also it has a sort of a problem we all wait to find the solution. We already know the love part as pairs but the progression is what we await more.
