There's no artist in this world that doesn't enjoy the dream that if they have bad reviews now the story of Keats can redeem them in their fantasy or imagination in the future. I think Keats' poem 'Endymion' is a really difficult poem and I'm not surprised that a lot of people pulled it apart in a way.
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.
