TV vets Marshall (director) and Kinnear team up for a sappy and predictable "Miracle on Melrose," a little piece of Capra-corn that feels like it lodged in your tooth. Cynical con man Tom (Kinnear) goes to work for the post office and gets stuck with a group of misfits at the Dead Letter Office, sorting mail for the likes of Elvis, Santa, and God. Even though he's merely working the ultimate angle for easy cash, the oddball team of postal workers think he's on a mission from the Lord and joins him in aiding the needy. Most unbelievable is the premise that single mom and love interest Gloria (Pitillo) can give the hardened criminal an instant psychological makeover. Broadly characterized supporting cast, including Conway and Metcalf, suffer at the hands of script. Strictly a star vehicle for Kinnear's budding movie career, it won't help. It also won't do anything for Marshall's downward-spiraling reputation. Ironic cameo from Christopher Darden as a reporter outside the courtroom, and Marshall himself as Postmaster General.
