After scouring the net for answers I'll go see the film again with fresh eyes but I thought Aaron had three plausible explanations for what the ending meant.
This can only mean one thing - poll time!
So here are his three options (the rest of his rebuttal censored due to the fragile state of my ego!):
a) Cobb doesn't escape from limbo... we don't see the kick so maybe the ending is all in his head. I mean that would suggest that the top keeps spinning long after the credits roll. I mean we didn't see what happened when he last spun the top...
b) Cobb has completed his mission. Saito kept to his word and Cobb has returned home (the kids at the end are played by actors that are 2 years older than the actors playing the kids at the end) this would suggest that after the cut to black... the top fell over and Cobb's back to reality, he dodges a bullet.
c) The whole thing start to finish is a dream. His wife died in Paris, he's flying to LA to “go home”... his reality does seem like a dream and is refereed to as such. None of the other characters on the plane talk to Cobb at the airport. Almost like they are all strangers who just all shared a 1st class flight with each other.
Which one of these options do you believe best fits your interpretation of the film... or doesn't it matter? Please use the poll on the top left of the blog...
One thing I can't argue with is Aaron's summation:
"Inception is in no way a 'perfect' film. It has flaws. But a classic film, loved or hated, it will become a film that could, and should, revive the spec scripting market in the US as well as sell the idea that big, original, large scale films... can still have an audience".
Amen to that.
