Harry and Tonto is best as showcase for Art Carney's great performance which deservedly won his Oscar. The film itself is decent in that it positions Harry in numerous emotional moments basically, honestly it all could have fallen apart but Carney keeps it all together with his honest performance. Every moment feels earned through Carney's work as he makes Harry a real man, despite the fact that he could have easily been a caricature in the wrong hands. The film is dated squarely in the seventies, particularly in some of the stops, especially one involving a prostitute. Even with that it the film works because Carney is so good.
