When Eames (Tom Hardy) said "You mustn't be afraid to dream a little bigger, darling" in Christopher Nolan's Inception, it may have seemed like little more than a throwaway quip, but that no longer seems to be the case. Nolan seems to have adopted it as a personal credo, since that sentiment is all over his latest project, Interstellar. Nolan returns to science fiction with a story that leaves dreams, Gotham and the Earth itself behind for the far reaches of space. It sends a small group of scientists, and audiences, on a journey that involves intergalactic travel, wormholes and a crisis that threatens to destroy all of humanity. It's epic filmmaking on a galactic scale, full of wonder and ambition, but the bigger canvas brings Nolan's flaws into sharper relief.
