The teaser showed us less than we would have liked, but, for me, the only thing I need to know is 'Directed by Christopher Nolan'. If his weakest movie, is TDKR, that's a pretty awesome track-record, and he's earned the right to have my $20 blind.
And what's this about Nolan not putting any ideas into his movies? He's calved out a niche for himself as a director of cerebral blockbusters. The morals of surveillance, the prisoner's dilemma, dreams versus reality, fear as a tool of leadership, individual versus society, etc. Not all are perfectly executed, and he often bites off more than he can chew, but props for the ambition.
And what's this about how Nolan will spend 45 minutes explaining worm hole physics? Did Nolan spend ANY time explaining how the suitcase dream machine worked in Inception? Not one second was wasted on technobabble. They didn't even give the device a name.
