thought provoking scifi In order to be effective, some motion pictures (more than others) require their audiences to engage in a behavior which is often referred to as the "willing suspension of disbelief". For a movie like K-PAX to work, not only is a suspension of disbelief necessary, but an abandonment of cynicism, as well. Because the movie tends towards melodrama, more hardened viewers may tune out without bothering to look beneath K-PAX's surface to discover that there are some interesting themes and issues lurking there. The premise, although not original, is intriguing, and the overall impact is helped immeasurably by the competent performances of lead actors Kevin Spacey and Jeff Bridges. Even considering its flaws (one of which is an overlong running length), K-PAX offers a worthwhile couple of hours spent in a darkened theater.
