I think ever since I looked up this trilogy on Wikipedia and saw the table of the Circle of Twelve, I have this question, and I think the fact that the films didn't really explain what's apparently in the books doesn't help; like, besides trying to rhyme and sounding mysterious, is there actually a purpose of choosing specifically those 12 gems, animals, trees and notes those twelve time-travlers supposedly each represent?
The below is featured at the end of chapter 5 of Ruby Red, Grace Shepherd later recited it to Gwen, (shame that it didn't make it into the films) (bold parts are added to indicate the gems (not bolded in the source material))
So, I don't think there's any film adaptation that could be exactly the same as their book source material, and most of the time people always say books are most def. better than films; but because time-travling really isn't my thing, I wasn't sure if I want to be invested and read the books, just to be disappointed later, I decided to watched the first two films first, since it's faster that way.
I'd say I enjoy them, but I don't think there's a lot of depth, unless there's A LOT they were able to cover. Because the third and last film doesn't come out until July 2016, I decided to start Emerald Green (audiobook, like I always do =P) right off, and see if the adaptations are decent enough that I can jump to the third book with all the info …
