Old time movie

This video seems pointless. I don’t understand what the relay does for this. It is really like a 30 second clip extended into a 5 minute show. Sometimes I think it is like a lay on words how it was replayed made some of the words sound different they were meant to be but I don’t understand what this is for. Was it made for shock value? I’m not sure what this thing was all about but I do think it was interesting how the artist chose this scene. It’s like an old beaver cleaver type clip. Where the little boy is mad and storms out and the sister I think says sorry. I thought it was a funny clip to choose.
