Ghostbusters is an exuberant, fully realized blockbuster packed with plenty of choice moments for repeat viewing. The cast is pitch-perfect: Bill Murray's easygoing comic gifts are at their sarcastic best; Rick Moranis is hilariously pathetic; and Dan Aykroyd and Harold Ramis do a wonderful job as the dorky, science-minded members of the crew. Aykroyd and Ramis also wrote the one-liner-packed script; the wacky, scary subject matter made the film understandably popular with children, but there's also sophisticated humor which can only be appreciated by adults. Providing a blueprint for the many copycat summer hits to come, director Ivan Reitman impressively balances the laughs with action and horror. The special effects have held up well with time, though the soundtrack and its catch-phrase theme song may feel a little dated.
