One of small pleasures of New Year's Day is seeing what old films the various terrestrial and digital channels dig out of their vaults to give a fresh airing since they don't have any original programming to fill the schedule. It's usually the same four or five old war films or comedies from the 1960s, but every so often an interesting little curio slips through. Such was the case this year, as Channel 5 decided to air a double-bill of The Wizard of Oz and its belated sequel, Return to Oz.
