I disagree - I saw this film almost 4 years ago and I still remember it vividly. I found it hypnotic and beautiful. Why does there need to be a point to it? It's only 7 minutes long, it's not going to be War and Peace.
As for forgettable, perhaps that's subjective. It was my favourite film of the night, and a friend of mine agreed that it was amazing. So there. At least two people loved it.
If you get a chance to see this film, and the others Glass commissioned for this set, I recommend you take it. Worst case scenario, you lose 7 minutes. It's a small investment of time with the possibility of great returns.
