The premise here is relativity. Time vs gravity. The story, if there is one, is pointless. Christopher Nolan has surpassed Stanley Kubrick in making a visually stunning but ultimately pointless piece of Sci Fi nonsense. Nobody can give me a convincing explanation of 2001: A Space Odyssey, but in 1968 it was jaw dropping. Interstellar's problem is we've seen it all before, and Nolan is not Kubrick.

Perhaps there is an analogy of the futility of life here, but it's spurious at best.

This ranks with Prometheus as an incredibly beautiful waste of my time.
