The worst part of all is the poor scripting, leading to superficial acting.
Dreyfuss' character is intensely repetitive and annoying, and Dreyfuss himself has the annoying face to match.
Holly Hunter's character is exaggeratedly self-centered, and Hunter herself indulges in serious overacting, as usual.
Brad Johnson was wooden. John Goodman made the best of it.
Furthermore, the whole death / ghost thing has since been somewhat overdone, and now appears rather lame.
Barely watchable only if you like old aeroplanes.
