*Slight spoiler alert*
I never read the books (honestly didn't even know they were a series) but I just couldn't watch past when Nory swept her way to the Fluxer's class to look at the kitten. Her whole character just made me want to scream. I kept pausing the movie because I would miss something important while I was rolling my eyes.
Without going into a full on rant about this movie, I don't think I will be reading the books anytime soon. Thanks Disney.
