My issue with the movie is not that the cast is all female, it's that the movie is a reboot. Given the fact that a few of the original cast members have cameos - and they are playing different characters - says to me the filmmakers went out of their way to shit on fans of the original movie.
With original cast members playing different characters - the filmmakers are saying definitively that the original movies never happened. A better course of action, IMO, would have been to write a new story and somehow link it to the original movies. One of the new Ghostbusters could have been the daughter, niece, whatever of one of the original Ghostbusters.
I'm sure they could have found a way to do the new movie and not say the original ones never happened - if they had wanted to. On the other hand (I suspect) that this reboot steals a lot from the original movie. And, therefore, if the reboot had been linked to the original movies (this movie existed in the same universe)... well, that would have been a lot of "history repeating itself".
Guess the writers weren't smart enough to come up with a new story. I should note, however, that I haven't seen the movie... yet. I am willing to give it a chance. Which isn't to say that I'm going to PAY to see it. Hypothetically speaking, that is... I actually haven't been to a movie theater in quite a long time. I'm saying that IF I paid to see movies in the theater I'd wait for some reviews first.
I'm thinking that this movie could turn out to be a huge dud. I mean, if all this reboot has to offer is that it rewrites the original (and does a mediocre to bad job of it) then it might not do so well at the box office.
