Rainbow Dash has a lot of cute faces in it.  Pinkie Pie's 'friendship' with Rainbow Dash is bordering towards "creepy", but I love megaphone scene.  At last, the Wonderbolt's training grounds~! *squee*  I like the cute pink pegasus. Can I call her "Sunflower"? And can she be my waifu [joke]?  Cloud Chaser has a cute voice.  Buffy "Yeah" Stallion is hillarious to watch.  Finally, they've made Spitfire into the strict, cold, harsh and manipulative "drill sergeant" type she always should've been. She looks cool in uniform, too.  Flight scenes remind me of the Acecombat games, cool and nostalgic.  Evidence that ponies have weather control technology! Take that, humans!  Lightning Dusk makes for a cool pony - too bad she's a SELFISH JERK!  Rainbow Dash's decision to sacrifice her place in academy for her beliefs is proof that she has become more noble. Respect!  Elements of suspense, which most episodes are lacking.  Watching Twilight Sparkle and Rarity flail through the air, classic  The powerful wisdom taught through the episode : "SELFLESSNESS" and "BE TRUE TO YOURSELF".
My only disappointment is that Soarin had no dialog, but it's okay because the story isn't about him.
And to you folks who like to complain, you're only bringing more things to complain about with your lack of gratitude and tendency for taking things for granted. You should be grateful that the story writers, editors, artists and animators actually took time to hear some of your ideas instead of throwing them all out the window. "Ponies gonna pwn. Haters gonna hate. Complainers gonna bring more things to complain about."
I'm not ecstatic about the episode, but it was really good. If Spitfire's voice is the biggest complain we have, then, heh, we're just picky But I too didn't like her here, which is weird, because I really liked how Kylie Metzger sounded in Powerpuff Girls Z (she was Buttercup's voice). Here she sounds as if she tried to hard - I hope Ms Metzger's throat didn't get butchered during the recording
