K-PAX is based on a novel and stars Jeff Bridges as a psychiatrist trying to figure out if his patient Kevin Spacey is an alien from another planet or just faking it.
Peter Travers K-Pax goes all too quickly k-put.
Rex Reed As a brainless laugh riot, it's as funny as a flu epidemic. As a drama, it's an unintentional Robin Williams vehicle sour beyond its shelf life.

Kirk Honeycutt Ultimately, the movie may puzzle audiences more than entertain them.

Claudia Puig A queasy amalgamation of Awakenings, One Flew Over the Cuckoo's Nest and Starman.
Moira MacDonald Flawed script turns well-acted K-PAX into a near miss.
Jan Stuart A syrupy melange of psychobabble and extraterrestrial mystery, offering further proof that planet Hollywood is made of cheese, with lots of holes.
Steven Rosen Its conflict is so understated, and takes so long to engage us, that the film is as flat as a stretch of Interstate 70 east of Denver.
Jay Carr Here [Spacey's] so good, and so compulsively watchable, that the producers never had to spend a dime on a spaceship.

Eric Harrison As billowy as a pillow.
Terry Lawson Everything about K-PAX seems to have been manufactured at Have a Blessed Day, Inc.
Philip Wuntch K-PAX never attains the soulful heights its makers obviously sought. But it's still worth a visit.
Bruce Newman K-PAX succeeds most often when it isn't blinded by the light of its own cosmic message. Its creators have apparently decided to embrace that message, seizing the moment -- and full credit -- with both hands.
Rene Rodriguez Gloppy and touchy-feely.
Paul Clinton (CNN.com) Inspirational and profoundly moving.
