Interstellar (just got back from the flicks) is not totally rubbish but it is too long and too slow. It reminded me of 2001 A Space Odyssey which was, however, far more convincing and believable at showing the inside of a spaceship (especially the Pan Am Clipper docking), despite nearly 50 years of advances in special effects. And small but significant observation - both films feature Hamilton wristwatches.
