Tex Avery has made some wonderful animated short movies, but this one does not belong to that category. It is something that looks like an adaptation from 'Uncle Tom's Cabin' with an Uncle Tom who tells the children about Simon Legree. Legree owned the whole city except for Uncle Tom's cabin. To save his cabin Uncle Tom changed it to Uncle Tom's Cabaña, a bar and dancing, to raise money. The evil Legree didn't like that and tried to kill Uncle Tom. Of course the children do not believe his fantastic story.
This short kind of has a racist look on black people, although it means well, I guess. It is one thing I don't like about it, but even if you are not bothered by that, it is not very funny anyway. I had no real laughs here and that is a strange thing with a Tex Avery short. Personally I think there are better shorts to watch.
