“Ghostbusters” (*** out of four) was an unexpectedly winning remake of the 1984 cultural phenomenon starring Melissa McCarthy, Kristen Wiig, Kate McKinnon, and Leslie Jones as paranormal enthusiasts who band together when Manhattan becomes under attack from otherworldly forces. Carried along by the fun chemistry of its lead actresses and affectionate homage touches to the original. Nowhere near as groundbreaking or hilarious as the first naturally but much more entertaining than the awful 1989 sequel and much better than many expected from its terrible coming attractions. Features amusing cameos from original veterans Bill Murray, Dan Akyroyd, Ernie Hudson, Annie Potts, Sigourney Weaver, (oh yeah) and Slimer and The Stay-Puft Marshmallow Man.
