Here's the problem with this- If the porn has a plot and is fun you won't know when to rub one out, because you are waiting on the next scene. Next thing you know the movie is over and you're still engorged. And I'll be damned if I'll watch a porno twice.
So this is what will save the porn industry? Aren't they just fucking the dessicated corpses of other franchises in a very loosely, barely-legal (but not in that way) way?
Not any more than the franchises are fucking themselves. The absence of Christian Bale in this already makes it better than the last two Batman movies.
