* BrokenBase: The TV series based off the books. Some fans say that [[TheyChangedItNowItSucks it didn't hold enough relevance to the books]] (amongst other things) whilst others felt it was a worthy adaptation with all the charm of the book series still intact.
** And then there's a broken base regarding the TV series itself: the third season. You had fans complaining about the re-casting of all the major roles; you had fans complaining that the series wasn't a ''Pine Hollow'' adaptation carrying on with the original cast; and then, of course, there were the fans who were just happy to see the show on the air again.
* MemeticMutation: Jokes about Lisa constantly falling ill or become injured in the TV series were widespread for a while.
* TearJerker: [[spoiler: Cobalt's death.]]
