I seen this twice and re-watching it again, I really think its underrated, also a very rare gem of early anime too.
Story - This story is really a twist; it has elements of the story of Thumbelina base off Hans Christian Andersen but goes its own way.
A woman whose fed up of her daughter's bratty attitude went to the town's witch and ask what to do, the elderly witch gave her a book called 'Thumbelina' and told her to read it to her daughter.
When she get home, she told her daughter Mia about the story and started reading it; a few pages in the
story the Mother felt asleep and Mia decide to read the book however she suddenly grow smaller and smaller.
Mia started her adventures, made friends along the way as well while heading to a kingdom to get back home and avoiding the evil witch and her magic.
The story like I said has some elements of Thumbelina and a hint of the Wizard of Oz too while still being its own.
Characters like the Toads and the mouse appear in the story as well with other creative characters.
Characters - I'll admit their pretty descent but the only grew we see is our Main Character.
Mia is indeed a total and ungrateful brat, like kids mostly are when she suddenly shirk down; she was helpless and scare while still being bratty but along her journey, she starts being less of a brat.
-The side characters are fun and cute too, Noble and Hoppy are super cute.
Art- The art is good old school anime style, bright and colorful to dark and mysterious. True gem.
Sound - Thou I did watch the dub, the voices were okay and I'll admit Mia's voice gets annoying at first but gets better later on.
The music is wonderful and magical.
The only down side I'll admit is the Witch Character, thou I won't say anything about it.
This is a wonderful story to watch, and I want to find the DVD to this since its a cute story.
