A little touch of "Ghostbusters" uncanny disaster, but highly original Reitman humorous romantic heroics, though Orlando Jones as Duchovny's unfortunate partner and fellow scientist was made a bit too farcical. Definitely a sci-fi parody, that uses toilet type references to ridicule intellectual (and authoritarian) pretentiousness, maybe borrowing from Jonathan Swift who hated the conceited snobby characters of his times."Evolution" is also a neat satire about disruption of natural law in modern society.

8/10
