Welp, looks like the film is a massive flop at the box office, grossing a mere $58 million global opening against a budget of $168 million. (Not including marketing costs which greatly inflates the break even point for big movies)
It flopped so badly, in fact, that it's the worst memorial day opening in 30 years.

Guess a Mad Max movie without, you know, Mad Max, wasn't such a good idea.
