But nearly all these books, aside from Venom, completely missed the point of the character. That her intelligence is balanced by her lack of wisdom and immaturity.
So for /co/, most of their first exposure was this little brat, rolling up and making everyone look like chumps, and calling them all idiots. It left a bad taste, even though the book she's actually from is cute and well-written.
