Sometimes a movie comes along that redefines a genre, that reshapes a movie landscape entirely - a wake-up call to an industry in the form of a seismic pop-culture event which pulls everything else along in its wake.
. . . And sometimes you just get a movie that's a load of self-aware adolescent humor wrapped around cartoonish violence and bare flesh.
Of course, sometimes you get, as Star Lord would say, a bit of both.
