The Hank Ketcham comic strip about a mischievous boy named Dennis Mitchell (Mason Gamble) becomes a film directed by Nick Castle (The Last Starfighter) based on a weak script by John Hughes (The Breakfast Club). Gamble is fine and Walter Matthau is persuasive as the grouchy neighbor Mr. Wilson, but Hughes spoils everything by throwing in a formulaic subplot about a criminal (Christopher Lloyd) who doesn't know what he's getting into by abducting Dennis. Been there, done that. --Tom Keogh
