[Brain 2000 is a sophomoric] future-fantasy about a child genius and his efforts to avert global catastrophe. Gann's plodding style didn't seriously detract from his straight novels, but it brings this attempt at comedy down to earth with an extremely dull thud. A miscalculation best forgotten as quickly as possible, and certain to disappoint those gripped by the heroics of The High and the Mighty and Fate Is the Hunter.
