Interesting set up introduces us to a disintegrating near-future world. There's an intriguing reference to re-writing history, along the lines of Capricorn 1, where planetary exploration is faked in a film studio. McConaughey is the astronaut turned farmer who takes a circuitous, and somewhat unlikely, route back to being a rocket man. Interstellar tries to get the science right but quantum physics doesn't make for the best dialogue. Neither are helped by dropping the spoken track way down in the sound mix. McConaughey's tendency to speak through gritted teeth doesn't help either. Although it looks great and is often very imaginative, the film takes too much time exploring dead ends and detours. At times, it felt a bit like a very long trailer for a very epic series. And it really does seem very long, without ever settling on a unified theme. The time anomaly aspects were good, but too much time was spent getting there.
