It's a lot easier to make bad porn movies than good ones. Which is why bad porn movies outnumber the good ones.
But women are usually the most passive participants in a porn movie. They often are the least responsible for making a poor quality porn movie.
It's the film director who has the most control over how a porn movie is made. And the stud banging the lady also plays a big role, because he performs most of the movement and action. If he does it wrong in some way, then the whole scene doesn't work well.
I think a good film director in one movie is likely to be good in his or her next movie too. It's best to search for porn movies by the names of their film directors, if you want to see something similar to what you've liked before.
