Christopher Nolan's Interstellar does a great job of keeping the story moving along at a steady and engaging pace. The reason I mention this is because the movie is partially inspired by the film 2001: A Space Odyssey , a film I've tried to watch on many occasions over the years and I still can't tell you how it ends. It just sends me to sleep - every time. If you've also struggled with that film and thought Interstellar, which also tries to depict space travel in a realistic manner, sounds like a difficult proposition then there's no need to be concerned. There's plenty to keep you tuned in and awake. That said, you'll probably get a lot more from this film if you have more than a passing interest in space travel, worm holes, black holes, relativity theory and time travel. Particularly if you're aware of some of the current research.
