The train barrelling through the street definitely hinted at that kind of crazy juxtaposition of ideas, but I would have loved to have seen a lot MORE of that in the movie myself.
I'd have to agree with you. I was expecting more bizarre imagery, but then again, this is Nolan. This is the most bizarre and visually wild movie he's ever done. He's usually pretty sane with his approach to his visuals.
I think I was honestly expecting more creative action sequences like the hallway sequence. However, I wonder if we saw too much bizarre imagery and too much of those weird dream state visuals that it would become stale after a while? If anything, Inception
leaves you wanting more of that, which is much better than wanting less of.
