LOL. That should confuse the hell out of Trixie if she turns up again. "I'm the REAL Trixie!" "Wut?!?!"
Agreed. Putting pegasi or unicorns in charge of feeding Equestria would not turn out well. Earth ponies are underrated.
Or the Harry Potter books. The Aurors seemed to be kept as busy as they wanted to be by assorted rogue wizards and witches in that universe, not to mention magical artifacts getting lost out in the Muggle world.
Well, Rarity is easy enough - Breakfast At Tiffany's.. If Holly/Audrey isn't Rarity, who is? Maybe "To Have and Have Not" for good measure.
For Fluttershy, the sweetest, saddest movies I know, Charlie Chaplin's "Limelight" and Jacques Demy's "The Umbrellas of Cherboutg" Then probably Demy's "The Young Girls of Rochefort," which is a fizzy, sparkling glass of champagne to the bittersweet romance of "Umbrellas." Come to think of it, "Young Girls" has Rarity written all over it as well.
Twilingt - the best of STNG, hooves down.
Applejack would probably go for a really good John Ford western or maybe Kurosawa's "The Seven Samurai."
Pinkie Pie - The Monty Python Catalog. Complete.
Dash? Maybe James Bond?
The AVERAGE unicorn is not over-powered. Generally speaking, an ordinary unicorn's magic is somewhat limited - generally relating to some aspect of their special ability - viz, Rarity's mending of the cab wheel. We as fans think automatically of the powerful unicorns/alicorns like Twilight, Starlight, Starswirl, and the other princesses when considering "unicorns." I very much doubt that an average unicorn - say Rarity or Vinyl - would be able of pulling off the magic that the particularly magic-attuned and highly trained graduates of Celestia's School for Gifted Unicorns could manage.
This looks VERY promising.
All of this. I can't get emotionally invested in any character that quickly. It even took me a while to really warm up to the CMC.
Fluttershy and Twilight were the characters that drew me in as well. I'm 55% Twi, 30% Fluttershy and 15% Rarity.
