The closet Christopher Nolan has ever got to making the Matrix, the film whose popularity paved the one for his own brand of cinema. The Matrix was a super cool high concept blockbuster, synthesizing many different pop genres. It utilized exposition as a weapon, bringing the audience in and asking them to go along with all the crazy shit that's about to go down. It asks you to question reality, and was *super* serious about the gravity of its concepts, and so preoccupied with presenting those concepts, that it basically steam rolled over little things like characterization, warmth, humor, emotional resonance.
Not that Nolan doesn't try for emotional resonance. He clearly thinks the Dom/Mal stuff is the real heart, that diving deeper and deeper into the mark's mind is a dive within oneself(I know this because, like all Nolan movies, they explain this theme out loud). And DiCaprio/Cotillard are actually quite good; star turns that command the screen as they navigate complex ideas. But Nolan's humans always seem more like "ideas" of people then believable flesh and blood ones.
And despite what some say, I'm not convinced it has all that much to say about the conscious and subconscious, about how fact shapes fiction and vice versa. This is not Mulholland Dr, and this is not Eternal Sunshine of the Spotless Mind.
What it is, to get to the positive part of this review, is an exceptionally compelling popcorn movie. It's intellectually stimulating on top of being viscerally satisfying. The filmmaking across the board is excellent, from Wally Pfister's Oscar-winning cinematography, Lee Smith's editing of several different dream layers coherently, Hans Zimmer's score that orchestrates and links everything together like symphony movements, and the phenomenal effects work. The last bit is crucial; some have taken Inception to bat for not being, IDK, The Cell or Enter the Void with psychedelic/hallucinogenic imagery. But the worlds have to seem tangible and real, not just for the heist team to do their job, but for the audience to be invested. The stunt work and practicality of all its spectacle is very key to getting under the movie's spell for nearly 150 mins.
Its often said heist movies are metaphors for filmmaking. Gather a crew of talented professionals, devise a plan, go about the job and improvise when things go wrong, and hopefully end up with a worthy prize at the end. I'd argue Inception goes one layer deeper(pun not intended) just by the sheer bravado of its concept. When we sit down to watch a movie, we put our suspension of disbelief on and view the director's dream. We want to be fooled, to quote another Nolan's film. Inception isn't just a heist film; its sci-fi, its James Bond adventure, its film noir, even domestic drama. Its a celebration of what movies can do: to capture our imagination and show us things that can't be done on the page or theater or even television. More than anything else, Inception is a spectacular showcase for the myriad of ways films can create dreams, and how top-shelf cinema can transport us into another reality.
