Ghostbusters 2016 reminds me of Sahara, in a way, a 2005 movie starring Matthew McConaughey and Steve Zahn. It performed reasonably well for a summertime action movie (though it was released in April), releasing #1 at the box office (at $18 million, admittedly far lower than Ghostbusters did) and went on to gross $119 million in domestic and foreign box office receipts. Unfortunately, the movie was not designed as a summertime action movie with an implausible plot (which it was, admittedly) but rather as an epic adventure based on a Clive Cussler novel with a budget of $130 million.
That's the same problem as Ghostbusters, it's performing like a summer comedy movie when it should be a big-budget blockbuster. With combined foreign and domestic box office receipts, it has barely made back half of its production values, not to mention the big merchandising push.
