I saw it on Friday. I rate it 'above average,' about on a par with The Prestige
It was a good movie, but in a way, its greatest strength was also its greatest weakness.
The premise was so unusual and original that Nolan had to devote a lot of screen time to big gobs of exposition. Too much time, IMO. And there's only so much excitement you can wring out of talking heads.
Now, that said--all of that set-up certainly did pay off when the heist began and the story really started rolling. So I left the theatre more than satisfied. But I still couldn't rate it "Excellent".
My fellow moviegoers seemed to enjoy it at least as much as I did. The chatter I heard afterward was all positive. I heard one guy say: "That was the most confusing movie ever--but also the greatest."
Even more amusingly, I heard another guy say: "Now, the real question is: are we really here, in this washroom? Or are we still watching the movie?"
