Okay, so Murray, Aykroyd and co. having to save New York and, quite possibly the world, from a gaggle of spooks - may just be an excuse upon which to hang cool special effects and jokey kiss-offs. But like more recent effects-laden genre efforts, Ghostbusters succeeds because it's charming in its own right, with sparky chemistry from Murray and Weaver, a constant stream of cracking one-liners and of course, the appearance of the Marshmallow Man, which is as absurd as is hilarious.
A hugely entertaining reminder of how good blockbusters used to be.
