This is another amazing animation from Disney. The unfinished look the cartoon has is very appealing, and the character design is very Disney. John Henry is a man who was once a slave, until the Emancipation Proclamation freed him and his love, who immediately get married. They go to strike it out and John Henry famously works on the railroad to get his wife and himself some land so they can be independent.
The short is fairly emotional and tackles some heavier themes for Disney (slavery, death), but does it nicely, in such a way that I could see young children be able to watch it without a qualm from parents. The music is very flavorful, being in the style of black gospel singers or backup singers. I could listen to this music for a while and not get tired of it. It's nice and fun for the kiddies to see, with some good messages about determination.
