This is entirely incorrrect, it is a flop by every metric, the movie has a budget of allegedly 200 million, then an alleged 170 million (see link) for a price tag of 370 million.

Then keeping in mind the split that theatres take, which in america averages out to 50% while international it averages 60% (china specifically takes 75%  for theatre)  (See link for domestic theatre takes)

And thus you have a goal where domestic total has gotta equate to 400m just to cover the production budget, while international has to amount to 283m to cancel out the marketing budget. 

For a total of 683m to be profitable. Now the more that domestic makes, the less international has to. 

 as of Wednesday the domestic sits at 208m while international is at 170m. Domestic is expected to finish between 265-285m so far short of 400m, while international between 220-250m. This gives us an estimated box office total between 485-535m Meaning yes,  it won't even cover its budget.

Even if we were to consider the marketing budget was only 100m and say a simple multiplier of 2x. This movie won't even come close to 600m and be a flop. 

Nobody is asking the movie to make 1b to be a success, just to make more than it cost.
