Point of fact: Emmanuel Lubezki was DP for Children of Men too.
And your strong reactions to the film in my mind reinforce everything I am trying to say about it. Malick definitely had too much time on his hands as it took him something like 20 years to make the movie.
I actually HATED Inception in a lot of ways because it attempted to be all "outside the box" and thought-provoking when in the end it just devolved in to an action movie with amazing special effects. Movies like that often leave my cold because they offer so much and then end up having nothing really to say for themselves. I'll take a mess of a movie that takes real risks with alienating its audience over the latter any day.
Take care all.
