My ideal reboot of Ghostbusters would be if they formed a new story around the film's original concept: A humorous movie about blue collar people busting ghosts in New York. Preferably in a similar vein to the new Jump Street movies.
Just give me a new story with different characters. I don't care if some of these characters on the team are women, but I don't want it to be entirely women, since that really does strike me as gimmicky.
Overall, I can't really say I'm a fan of the idea. It would take a lot to win me over, especially with Paul Feig. Bridesmaids was fine, but The Heat was terrible.
My biggest fear is that they cast Melissa McCarthy, and she goes around doing her usual Melissa McCarthy-isms as she busts ghosts.
