Could it not be argued that Gonzo flicks are in fact documentaries of some sort? Gonzo, by its very nature, consistently 'breaks the fourth wall' in that the director and crew are not only acknowledged, but often also interact with the subjects, either verbally or physically.

Also, as other posters have pointed out, the notion of what constitutes a 'storyline' will vary from person to person purely in terms of artistic taste...many gonzo directors have cheesey little lead-ins to their scenes. Will this be enough to get them off the hook?

Following this sort of logic, how long before the MPAA is excising the opening credits sequence from James Bond movies? It doesn't serve to advance the plot (nor does it have a plot), it's just a montage of naked women in silhouette moving about sexily.

Indeed, why stop at pornography? Any sex scene in a mainstream movie which doesn't serve to advance the plot (the woman becomes pregnant/one of them is being unfaithful/one of them gets HIV, etc.) must surely be just as frivolous as porn if it tells the viewer nothing more than 'these two characters really like each other'?

Interesting times ahead, no doubt about it...
