There comes a point in your moviegoing life where you look at the screen and then you look at the world and you ask 'What is going on?' You want the movies to show you the chaos and mess and risk and failure that are normal for a lot of us. Generally the movies hide all of that.
But short films are not inferior just different. I think the short gives a freedom to film-makers. What's appealing is that you don't have as much responsibility for storytelling and plot. They can be more like a portrait or a poem.
