It's said that Christopher Nolan spent ten years writing his screenplay for "Inception." That must have involved prodigious concentration, like playing blindfold chess while walking a tight-wire. The film's hero tests a young architect by challenging her to create a maze, and Nolan tests us with his own dazzling maze. We have to trust him that he can lead us through, because much of the time we're lost and disoriented. Nolan must have rewritten this story time and again, finding that every change had a ripple effect down through the whole fabric.
...The movies often seem to come from the recycling bin these days: Sequels, remakes, franchises. "Inception" does a difficult thing. It is wholly original, cut from new cloth, and yet structured with action movie basics so it feels like it makes more sense than (quite possibly) it does. I thought there was a hole in "Memento:" How does a man with short-term memory loss remember he has short-term memory loss? Maybe there's a hole in "Inception" too, but I can't find it. Christopher Nolan reinvented "Batman." This time he isn't reinventing anything. Yet few directors will attempt to recycle "Inception." I think when Nolan left the labyrinth, he threw away the map.
