I don't follow any porn star in particular... I simply open the homepage of a popular porn site, bring the pointer over the thumbnails to get a preview, and click on whatever seems interesting.
Among the names I know, Sunny Leone was arguably the best porn star of my generation, so obviously she's great. I hope she receives acclaim in mainstream movies as well, and her roles aren't limited to showing skin.
Ashley Starr is beautiful, but her movies are pretty generic... except that one BDSM movie she did. It was awesome.
Nina Hartley talks a LOT! Blah blah blah blah blah... I never told anyone "you talk too much" again, ever since I started watching Ms. Hartley's work.
April Flowers is cute and underrated.
There are some familiar faces in Japanese porn, mostly in their early/mid 40's, I'd say... But I can't seem to remember their names. They also have fantastic skin, probably from all the raw fish they eat.
So that's pretty much it. I prefer movies with a little plot and a good setting, plot as in something more than two people simply meeting in a room and deciding to f***; good setting as in something that's not a black sofa/white bed on a white background. The camera work should be bearable. Thankfully my countrymen are finally figuring out that the camera should be pointing towards the people in action and not the walls. Finally, the acting should be just right, overacting is a bit of a turn-off. Yeah I'll stop now.
