I agree to an extent. She's similar to Lisa in The Simpsons. She was okay in the first few seasons as a straight man/smart foil. After than every episode focusing on her is a immediate skip on rewatch, she became an annoying know-it-all that was also simultaneously the reason for the episode happening.
Except for the episode where she made an art sculpture out of beer cans or something and got roped into being a part of an art exhibit for retards, I think that came later in the show's run and it made me laugh pretty hard.
