In 1984, Ivan Reitman directed a blockbuster summer hit called Ghostbusters . Now in the year 2001, he has released his newest directorial effort, Evolution .
Evolution is merely Ghostbusters remade with aliens taking the place of ghosts.
There is even an alien version of the giant Sta-Puf Marshmallow Man which appears in the closing reel. At least Reitman realized that when one is going to copy a formula, it helps to copy one that works. Evolution , though hardly original, is funny. Sometimes extremely so. When a meteor strikes just outside of town, they go to investigate and discover one-celled organisms oozing from the rock.
