As to whether this film is a success. I think the answer to that question is, "a success to whom?" Movies are made by many different individuals working together, performing different jobs, with different goals, etc. The primary goal of the film as a product of the Walt Disney Company is to generate profit. Whether or not it does that remains to be seen. The goal of the film as a work of art can vary depending on who you ask. The film isn't a critical success, so you could argue the film isn't successful at being art. However the film is well liked by those who have seen it, so you could call it a success in that regard.
I do think, objectively though, that the most idiomatic definition of the word 'success' as it applies to a movie would
be financial success, or mayybbbeee critical success. Currently the film is doing pretty well domestically, but since the film was a global release I'm not sure how much that really matters. In the nicest way possible.....the world does not revolve around America. The Walt Disney Company is based in America but it is a global entertainment company, and for it's products to succeed they must do well where they are sold, which is across many different countries. Now, whether the film turns a profit remains to be seen. Will the film taper off or go on strong, I really don't know. It's not possible to say whether it is a success yet in the present tense. Whether the film is a critical success....well, the film currently holds a 59 on metacritic, which is not very good. On a college/high school test, that would technically be a failing grade. On RT, 68% of critics rated the film fresh, which isn't terrible but for a film that doesn't take many risks, it's also kind of disappointing. For reference, the Jungle Book remake made it to a 94%, which is a closer to what "good" blockbusters usually get because again, blockbusters typically don't take many risks and are designed specifically to appeal to broad audiences. So they usually appeal to most critics. So 68% in my opinion is not very good, I'd call it pretty middling. And 59 on metacritic is also not good. "Meh," really.
So is the film a success. That depends on what you mean by that question. It's doing "fine" right now in my opinion. It could end up being a financial failure but it's impossible to know for sure as of right now. Critically the film is not what I would call successful, but I guess "success" is relative.
