SPOILS OF COURSE
This is fantastic on IMAX, so glad I could wait.
First of all I love Nolan's film craft, along with Fincher right now he's the best at merging real awesome sets and cgi, all his shots are flawless.
Cobb’s children did not age when they reunite, which hints to the possibility that we remain in a dream. Cobb repeatedly asserts the notion of planting the seed of an idea deep into the subconscious to take root for its purpose to take effect. If this is all a dream, imagine how deep Cobb has descended.
more than the lack of aging, they are wearing the same clothes, and to me when he entered that room and looked exactly like he remembered that meant he was still dreaming, even the day light was the same.
To me is crystal clear that the final scene is a dream, since he once said in the film that he needed to reconstruct that image of him seeing his kids, and by having seen their faces a huge weight will be lift off him and all that regret of not seeing them at moment will be gone, this imo will lead to a path of waking up.
I was listening to an a/v podcast on this movie and they brought up an interesting point, that as fun/frustrating as it might be to debate the ending, ultimately it doesn't really matter because it doesn't seem to matter for Cobb. Remember he spins the totem but walks away and never looks back.
But he doesn't have a chance to wait and see for himself as he is timely interrupted by his father, so he directs his attention to him and finally seeing the faces of his children.
In conclusion, Nolan's dreams are better than mine (so far). btw, I dreamt that after the final shot there was another scene, Cobb was trying to escape and he was on a building that started to separate from the city ( it was going up), cars that were parked around it started to fall, then the damn alarm clock went off.
