Janelle Riley writing for Variety:
He's in an incredibly tough position, because there are people who love the original movies and are worried about newer ones tarnishing the originals, despite this being set in a completely separate universe rather that being a direct sequel. And on top of that, he has people/misogynists criticizing him most of all for casting it with a female ensemble.
As a fan of the franchise, I don't see what the big deal is with that decision. There's nothing about Ghostbusters that specifically states that they have to be male, and as long as the story and characters are good, then I don't see why it should matter? Plus, if you're going to reboot a franchise and want to do something different then Feig is definitely going about that the right way. And bravo to him for that.
Brilliantly put and a very fair point (it's funny because it's true).
I often like to think back to the Batman franchise as a good example of stuff like this. Tim Burton got the same flack for having the audacity to cast a comedian (Michael Keaton) as Batman. And that movie turned out pretty great. Then Christopher Nolan came along to reboot the franchise, which left a lot of people angry at Nolan for trying to reboot a movie franchise that people felt was already a perfect couple of movies with Keaton in the lead role. And I think it's safe to say that the Nolan franchise has since generally been regarded as an overwhelming success.
Prior to the announced casting of the new Ghostbusters movie, Bill Murray went on record to say that he'd love to see an all-female cast with Melissa McCarthy being involved. That in itself is enough of a green light for me. As for how well the movie turns out, we'll just have to wait and see. But if it's going to be a success or failure, then that's going to ride on whether or not it's a good story - not because of the sex of the cast.
