Hear that? It's the sound of Inception, Christopher Nolan's mind-bending, puzzle box of a blockbuster from 2010 - a film that, six years ago, arrived in theatres to mass declarations of, "Oh, so this is the best sci-fi film of the last decade, is it? Okay!"
With its multi-dream layer narrative and crazy twists, Inception came post-Dark Knight and pre-The Dark Knight Rises, blowing minds the world over. People watched in awe, and then they went back and watched in awe all over again, struck by the visual effects, intriguing mythology and an ending that kept you guessing long after you'd left the theatre and started planning your new career as a "Dream Stealer."
Nowadays, Inception might not feel quite as innovative as it once did, but it's still a defining film of its era and one that has no doubt carved itself out a nice little space in the pantheon of modern sci-fi classics.
