Nearly every instance of a Guardians of the Galaxy trailer shown for the past six months at multiplexes nationwide is immediately followed by the same whispers. "Who are those guys?" "Have you ever heard of these superheroes?" "Are they related to the Avengers?" Don't beat yourself up if you've never heard of the Guardians.

Marvel Studios, well aware of this, takes this as an opportunity to cut itself loose from comic book continuity, giving director James Gunn a considerable amount of creative license to come up with a bouncy, hilarious bauble, an almost $200 million near-throwaway that also happens to be one of the best cinematic adventures of the year.
