Holding amazing against Rogue One

Rogue One is opening to an impressive 140-150 million, but Moana is the real story here. Despite being against a 4 quadrant movie that is probably the hottest franchise in the world right now, Moana is looking to hold at a stunning 20-25%, for a 13.8-14.8 million weekend.
While it's not a perfect indicator of anything, it shows that there is still interest in Moana against other family-friendly movies, and gives even more signs of a good hold against Sing.
