These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Tales of the Frog Princess
Dork Age: When exactly it set in is up for debate. General fan consensus seems to be that the first four books were solid, Salamander Spell could've been a lot better, but it also could've been a lot worse, Dragon Princess was weak but bearable, and the last two books were really not that great.
Most Wonderful Sound: The narrator for the audiobooks. As far as the fans are concerned, her voice is Emma.
Periphery Demographic: Aimed at elementary schoolers, and indeed, many fans do discover the books at this age, but continue to love them even as teenagers. And of course, there are fans who discover them as teens.
The Scrappy: Audun. Almost NO ONE in the fandom likes him.
