Dem's a 12 year old boy! Ban him!

I do get where your coming from in some respects though Dem, but I've never found it to be a necessity. Even in the sub-genres you've mentioned, I've never found myself thinking: "that really could of done with more sex and nudity" once a film had ended. They're just secondary elements (added bonuses if you will) and whilst sometimes beneficial, never really take precedence over the plot, atmosphere, cinematography, effects, score etc. - they are what constitute the bulk of the film package for me, sex and nudity is often just the bow on top
