Ignoring the rest of the article, because Paul Feig plays the victim card before the movie is out, I want to highlight this:
As opening day approaches, Feig can’t help but think about the stakes of making a $150 million movie. “A movie like this has to at least get to like $500 million worldwide, and that’s probably low,”

With that said, I think it is safe to assume, that ghostbusters is not succesful, and that just being production budget costs are not metric of success.
Add: I need to travel, will add more of my thoughts when I make it to work, and have a bit of time to kill.
