$40 million opening is certainly not a flop. Everyone both screaming to go see it because feminism and cheering it to fail because third wave SJW feminazis forgets that the majority of people aren't listening to either of them. The majority will either go see this movie if it seems like it might be a good watch for them or not if it doesn't and don't care about the political noise. I imagine this movie is going to do pretty good with families because whether or not the parents generation wanted a Ghostbusters movie without the original cast is way less important than the fact it there are only so many movies that are equally as acceptable (even if not beloved) to the six year old as to the nine year old as to the fourteen year old for a family outing to the movies and this probably fits that bill.
