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: Rainbow Magic
Awesome Art: Return To Rainspell Island was a co-production with a Japanese studio, and it shows.
Some of the books, such as Elisa the Royal Adventure Fairy's, have very detailed art.
The picture of the baby penguin in Pia the Penguin Fairy's book perfectly encapsulates its cuteness.
The fairy designs are very cute and easy to tell apart.
Awesome Music: The music for the "Create a Fairy" game on the website.
Mary Sue: Kirsty and Rachel can come across as this sometimes.
Rooting for the Empire: Given the heroes' generic personalities, some people read the series to see how close Jack Frost gets to winning before his plans are foiled.
Seasonal Rot: The franchise is becoming too repetitive for its own good.
Surprise Difficulty: Some of the games on the website are pretty hard. Case in point: Hide and Seek. Instead of simply clicking on the gems, you have to actually drag them to their spot on the cup. Failing to do so ends with the gem in question moving to another spot in the room. Also, Jack Frost shows up about every twenty seconds (sometimes even more often) and destroys all the progress you made, forcing you to start over. There is also a time limit, as well as fake gems. The third round has 21 gems to find. Have fun.
Also the Fairy Race game. Sometimes the obstacles are so close together that maneuvering your fairy between them is impossible. Luckily, you have a total of 21 lives- 7 fairies with 3 lives apiece.
