I think you're probably right about that. And, I don't see a problem with it.
If it was Chris Pratt, or Bradley Cooper, or Nick Offerman, or Kumail Nanjiani, or Ed Helms, or Bill Burr, or Keegan-Michael Key, or Jonah Hill and Channing Tatum (neither of those separately, though), or Keenan Thompson, or Jason Sudekis, or Paul Rudd ... guys would be far more enthusiastic. Because that's what Ghostbusters was. It was a guy's comedy. Probably one of the first 'bro' comedies.
You can't remake Animal House with a bunch of chicks and expect fans of the original to be pleased with the change. Because it's too different. You also can't take Fried Green Tomatoes, or 9 to 5, or Big Business, or Steel Magnolias, or whatever other classic female-targeted comedy, and remake it with a bunch of dudes and expect to retain your original female viewers. Because it not only betrays the core purpose of the original ... but it smacks the original fans across the face by taking something they loved and intentionally rejiggering it for someone else completely.
I have never met a woman that gave much of a damn about Ghostbusters. My wife certainly didn't. So ... why, after all this time, would you make a reboot targeted at her instead of the guys who grew up with this? It is telling that the people who are irritated at this are the longtime fans of the original ... and the people who are enthusiastic about this couldn't give a good goddamn about the original. They've killed off their original audience in favor of a different, more politically fashionable audience. Which rightly pisses off the fans.
