I love Animorphs, but did anyone else find it annoying that in every single first chapter of each book had the same introduction? "There is a threat with yeerks, and they are real. Yes, people all around you could be controllers. This is all true, and we fight back. A blue centaur alien found us and gave us power to change into any animal we want." It allowed for anyone who started the series in the middle to have some understanding, but seriously, it got old after 20 books.
