Wise words from Ishi Rudell (Director for Equestria Girls: Rainbow Rocks the Movie). While the book may follow the storyline (still unconfirmed), it is far from the actual movie script. If you liked the first Equestria Girls (and despite humanizing the ponies and Flash Sentry's Waifu stealing), it seemed like a lot of you did), you can probably expect the same level of quality in the second one.
Update: Rainbow Rocks the book is a prequel
