I’m so buying the score once it’s available in my region.
The thing about The Mane Six is that they’ve saved the world multiple times, but it’s mostly just by virtue of passing various tests of character. Otherwise, they’re not exactly world-saving materiel. Having thought about it, I think The Movie is an exploration of this idea.
The Mane Six are part of two separate yet overlapping stories. In one story, they get lost in the desert, Rarity nearly gets them sold into slavery, and Rainbow Dash gets them spotted and gets the pirate ship destroyed. They nearly get killed multiple times on their adventure. The Mane Six are no match for this scary outside world, and Twilight is the only one willing to do what’s required in order to save Equestria.
In the other story, The Mane Six escape the invasion, cross the desert, escape their pursuers, convince others to join their cause, manage to get a ride to Mt. Aris, find the Hippogriffs, and convince The Queen to help them. All of this was possible because they were good ponies and stuck together. The Mane Six are plenty qualified to take on the world, and Twilight ruined everything by abandoning the virtues that let The Mane Six succeed.
