I have faith in the cast and Director, Paul Feig, on this one. His track record is great and the concept is a proven winner. I think it will be excellent, but totally different than the original. The major difference (besides the sex of the characters) will be the pace and action. The original movie had tons of dialogue that took time to set up the ghostbusters and had little action before the final scene. This movie looks like the 2010's super hero version of the original. The jokes will be there, but the action will be over-the-top and often.
