I'm afraid to look at the Dutch version....
Even although Disney is a lot of times better in Dutch, I don't want to see if Hasbro can do the same.
So I watched 'Suited for Success'. It was terrible. The only voice I don't hate is Fluttershy.
AJ has no accent.
Rarity has no fake high class accent.
Pinkie Pie's voice no longer fits her personality.
Rainbow sounds like a man trying to voice a female character.
Can't explain Twilight.
EDIT: Is Fluttershy even singing in your version? Because she sounds like she's dying.
