If you spend some time at the EBI forum, you get the impression that the facial looks and anatomical features of porn girls are more important and interesting than the porn movies these girls appear in.....
No offence intended, but to me that is a very strange idea.
I like to buy porn movies on DVD. The purchase decision is based on the DVD's availability in shops; the price; and of course content and quality.
When it comes to content and quality, the best indicators are for me the porn company and the director.
For example if I want to buy high quality American anal oriented hardcore, I will focus on the company Evil Angel and then on the directors Jake Malone and Christoph Clark.
The female cast is not really my concern. I have no doubt whatsoever that directors like JM and CC will pick some hot girls who will come up with a good performance as required. Most of the times I don't recognize the girls and I don't know their names. It is more important that I can check the trailer to see if I like the action. Online reviews can also be helpful.
