!!For the TV series:
* SecondSeasonDownfall: Like ''WesternAnimation/TheMrMenShow'', Olivia (owned by Chorion at the time with some of the staff who worked on the same show), suffered some changes that fans disliked that likely caused the show to be canceled (also somewhat karma for Chorion as they fell under bankruptcy a year after the show ended). These changes include:
** [[DemotedToExtra Julian not appearing]].
** Daisy and Francine having their personalities swapped.
** The show changing from a realistic tone to DenserAndWackier, making it more hyperactive.
** Songs being added and Olivia singing at the end.
** The O gadget.
* TheyChangedItNowItSucks: Season 2 for many fans. With [[DemotedToExtra Julian not appearing]], Daisy and Francine having their personalities swapped, the addition of songs (especially the one Olivia sings OnceAnEpisode) and the O gadget, plus the switch from a realistic tone to DenserAndWackier from the show, people were unhappy with the changes.
