Ivan Reitman’s enjoyably silly (and occasionally genuinely scary) supernatural blockbuster about a team of amateurish ectoplasmic exorcists rescuing New York from a plague of ghouls was the most expensive comedy of its time.

Ghostbusters is like romping through Disneyland's haunted house with Bill Murray.

Ghostbusters is primarily a showcase for Murray, who slinks through the movie muttering his lines in his usual cheeky fashion and getting off an occasionally hilarious crack that proves he's thoroughly enjoying himself.

"Ghostbusters" is a very funny movie until it gets a bit bogged down in its gaudy special effects.
