I don't see Mulan doing good as I think people are getting tired of the live action remakes. I have met very few people who have legitimately liked most of the remakes as much as they were hyped up to be. The only remake I actually liked was the Jungle Book, the rest have been sub par at best imo.
The Box office of over a billion for Lion King and Aladin says people are not tired of these. I saw the Mulan preview, I think it could make 1/4 billion in China alone. It should be another big hit for Disney.
There came a time when the Old Gods died! The Brave died with the Cunning! The Noble perished locked in battle with unleashed Evil! It was the last day for them! An ancient era was passing in fiery holocaust!
