Interstellar. It's a hell of a lot better than I remember it being, guess it benefits from repeat viewing. Knowing the story, I was able to go along with it a lot more, when originally I'd spent most of the running time mentally nitpicking (and I'm not a natural nitpicker).
My only serious complaint this time is that Dr Mann's motivation and goal were ill-defined. Other than that, it's just fantastic - such a smart story, affecting performances, timeless production design and effects, by far Zimmer's best score for a long time. It's my new favourite Nolan film.
