Genial, sporadically amusing timewaster

Bridesmaids director Paul Feig’s recipe for “reimagining” the iconic 1984 original: start with a troupe of former SNL comics, add the expected special effects (lots), and stir in too much generic action and Ghostbuster-spook battles. Overcook. Must have been low on humor.

This genial, sporadically amusing timewaster is not terrible. But it’s overlong, fairly pummeling, and unnecessary. This has nothing to do with the talented all-female GB team. In fact they save this rehash. Great chemistry, spiced by a few cameos by the original cast. They just aren’t given enough funny things to say. (116 min)
