FXRant posted a thoughtful piece on Playing With Expectations (and the 180 degree rule). Here's an excerpt:
I love filmmakers who don't feel the need to sink their film to the lowest common denominator; filmmakers who, even within the context of a blockbuster-type film, give their audience a bit of credit for their intelligence. These writers and directors accept the fact that they are working within a framework of expectations - not simply the expectations of the traditional Hollywood narrative structure, but genre-specific elements for which audiences have become accustomed.
The "Casino Royale," "MI3" and "Ratatouille" clips are examples of intelligent screenwriters playing with the expectations of a clever audience. Of course, this technique of toying with cliches and turning them into something more interesting only works in the hands of truly innovative filmmakers."
