Hancock is a perfect example of GENERIC EVOLUTION. Generic evolution is a syntactic variation of the semantic elements that define a genre, most notably the Iconography, Character, Narrative Structure and Themes. In lamens terms, it is the knowlegable manipulation of the material that makes a movie, in this case the superhero movie, to fit contemporary culture and tastes. According to Thomas Schatz, a well known generic theorist, every genre goes through four stages of generic evolution, the last of which is baroque, which is the stage at which reflexivity overrides the core ideals of the genre. Other movies like Super Hero Movie(or whatever it was called, by the guys who made Scary Movie) represent the parody, or really in there case a farcical view of the genre. Hancock seems to be more of a Post-modernistic view of the superhero genre, because it really doesn't seem to show a knowledge of the genre's history or traditions, or even really refer to the history of the sub-culture of comic books that the superhero movie came from in the first place. It's just a superhero movie based on the set of guidelines that other superhero movies has built, its media made from media, not from a source material (the comic books).
Do I actually understand what the hell I just said?! Only vaguely, goddamn Genre Theory class. The movie looks like it'll be good for some action entertainment and some laughs, and I'll fully be able to judge the movie on itself, not on its predecessesor or a comic book or novel that it's based on. That usually is a good thing. I'll go to see it in theaters, and unless its really bad I probably won't have anything bad to say about it. Things that go boom, woo.
