The idea that worked so brilliantly in Big - a grown man playing a child - falls flat in Clifford. Whereas Tom Hanks played his role with innocence and wide-eyed curiosity, Martin Short plays 10-year-old Clifford as an obnoxious brat, who thinks of ways to punish the adults around him if he doesn't get his way.
Charles Grodin plays Clifford's uncle who watches him for a week to impress his fiancee, Mary Steenburgen.
Grodin and Steenburgen do their best with the sappy material they have to work with, but Short, who might be a funny sight for a few minutes, is increasingly annoying with every scene. He has one silly expression that covers his every emotion.
This is one comedy that was difficult for both kids and adults to sit through.
