nah, i'd just call them good. not every character is good, some are really underdeveloped, but others get plenty of time to develop and even if they only ever play a role in a single chapter of the story, that role is usually competently written.

ymmv, but if we're using stuff like enstars and twst as a metric (and the anon i replied to was), they're at least as well written as those characters are
