I'm sure it will be good. Ivan Reiter, the director of Ghostbusters 1 and 2 is returning to direct it, I believe, and of course, it would also be writen by Dan Aykroyd and , most likely, Harold Ramis as well.
Remember, Ghost Busters isn¡t just any old franchise, it was one of the most sucessful franchises of the 80's, and I seriously doubt that the actual creators of the movie could destroy it...
