Really, really boring, probably because it's way below my reading level. But still.
I only came for inevitable ball scene at the end of these special editions. I love seeing the dress designs and the actual hall for whatever wedding or celebration of "I was under a spell, but the Thea Sisters did a bunch of near impossible tasks with ease because they had the power of FRIENDSHIP, and saved me with the crystal gem!". Because as boring as these books tend to be, the art is always, always phenomenal. I found myself saying "wow!" and gasping aloud a couple of times. That never changes and that's a constant I love about it.
But before I get gushy about the art, I just want to say I'll need more than two hands to count the number of times they used the word "mysterious". C'mon. A thesaurus exists for a reason.
