And that's kind of the problem. The reason the crests worked in Digimon Adventure was because the characters were written around them. Here it's the opposite, where we already had our characters in place except now we're trying to ham-fist the crests into their personality because they weren't planned for ahead of time. Adventure 01 didn't have that problem because the characters were essentially written with their crests in mind from the get-go. Well, except for Kari but she's kind of a Mary Sue anyway so she doesn't count.
