Everything with RD was great. She has certainly grown as a character and become far more mature while still possessing the same cocky attitude that made love her in the first place. However, as much as I enjoyed the scene with RD saving her friends I really wish they had no involvement beyond the opening. The rescue scene could have worked just as well with the other recruits. This was supposed to be RD's story and the rest of the mane 6 seemed to be just interfering. Everytime they cut away I just groaned because the story wasn't about them it was about RD.
Secondly Spitfires voice/personality, taking a character who's personality has been well established and turning her into a complete ***** is just plain lazy. Spitfire's is the captain of the Wonderbolts, not a drill sergeant. So now's she playing double duty as a trainer and captain? Would it have killed them to create a different character to play the drill sergeant?
