Greg Kinnear's limited talents are stretched too thin in his role as a selfish con man who becomes a nice guy after being sentenced to work at the dead-letter department of an L.A. post office. Deciding that it's nicer to help people than rip them off; Kinnear's character leads a band of mailroom wackos in responding to the entreaties of those who write to God for divine help via the mailbox. The film strains to be reminiscent of Frank Capra's populist comedies while also covering a lot of other; far less sophisticated comedy bases. Laurie Metcalf is mostly irritating as a neurotic postal worker who tries to keep the hero out of jail; when it's discovered he's removing dead letters from their basement burial ground. Hector Elizondo does his dignified thing; and Jack Klugman and Roscoe Lee Browne are somewhere in the mix. Tim Conway is the best element; a half-crazed mailman with the only shred of real humanity in this supposedly human tale. --Tom Keogh
