Watching Venkman, Stantz, Spengler and Zeddemore battling Zuul and his minions as an adult is about as much fun as movies can offer. As a kid, it’s a different matter. No film, perhaps excluding Withnail And I, changes genres faster as you get older than Ghostbusters. It’s horror-turned-comedy-turned-‘80s-nostalgia fest. The funny stuff (“It’s true, this man has no dick”) isn’t so important when you’re, say, eight and there are giant marshmallow men to be gawped at. The scariest ‘busting moment is tough to pick. Zuul is pretty fearful – hey, they bring ‘em up tough in ancient Sumeria – but the prize goes to the New York Library’s resident ghoul unleashing her full toothy terror on our favourite parapsychologists (we were hiding behind our cinema seats at the time). It’s Sam Raimi for the under-nines.

Scariest monster: The Gatekeeper and the Keymaster, big puppies with the big plans. They’re the kind of mutts you can pick up at the Battersea Home For Demonic Psycho Dogs, but you’ll need a very long leash.

Spookiest scene: That library hag, unhappy to be disturbed while (possibly) perusing the Dan Brown section, is a landmark in jump-shock history. Booooo!!!

Redeeming ‘aww-shucks’ moment: Surely it’s Slimer, the acceptable face of ectoplasm, affectionately redecorating all he encounters an interesting shade of green.
