Yeah. Those suck ass... and while it might be true in a literal sense, I don't mean it that way.
But...
We REALLY shouldn't compare them to SERIOUS attempts at live action movies (like unfortunately, Dragonball). Yes, they could be just as bad as the serious attempts at live action. But there is one big difference.
The serious attempts are 'trying' to be good. Dragonball is an example where it will fail. But some guy out there thought it will be good and 'respected'.
AV porn only attempts to be porn. The people behind it don't care about quality. Just an excuse to have sex in costumes. It's like, as I've said, comparing a porno movie with an actor in a cheap batman suit to The Dark Knight. If you try and put the first in the same breath as the second, you're going to be losing a lot of credibility.
