 NBC's Sunday night strategy failed, however, because Red Skelton's program suffered from excessive use of rerun episodes when Skelton unfortunately fell ill. Of the network's other filmed series, "My Hero" was "a weak slapstick vehicle" while "Doc Corkle" was "generally regarded as the worst sitcom of the new season".It lasted only three weeks before cancellation (replaced by the return of the live "Mister Peepers").With the exceptions of "I Married Joan" and the revival of "The Life of Riley" starring William Bendix in January, NBC would have little luck with filmed programs during the 1952–53 season.
