Overall, my family rated the movie a B-. It begins very slowly with the use of a lot of technical terms that quickly bored my pre-teens. The action sequences were unrealistic. There's no way that Cusack's character could maneuver a limousine so deftly. Neither could the pilot later in the movie fly through torrential winds and volcanic ash with only 2 flight lessons under his belt. That stated, the special effects were pretty impressive and Woody Harrelson's played the wacko genius brilliantly. Those two highlights are what kept us in the theater long enough to see the ending.
