Via a magic mirror, Twilight Sparkle travels into an alternate universe in order to recover a crown that was stolen from the Crystal Empire. Upon her arrival she is horrified to learn that she has turned into a human.
Okay, first off, one should really just watch this as part of "Friendship is Magic."
On its own, it would lose a huge amount of the fun and, well, most plot context.
That said:
It is a nice movie, as silly-cute fun as the regular show, clearly written by the same people.
I'm still not a fan of the human designs, the animations are kinda mixed, and the end fight was sadly very deus-ex-machina-y cut short, I would've loved an actual fight, but overall a nice movie and some fun spins on the origin show's characters.
Scootaloo actually looks kinda nice as human, Pinkie is crazy-lovely in every dimension and Spike is a good boy either way, too.
This opens up quite some new ideas on how other dimensions might look and work like.
Also, I liked the Highschool Musical song number. 😁
So, if you enjoy Friendship is Magic, this is a good addition between seasons 3 and 4, even if ponies still are superior! 😁
