1). Small videos that are split into different parts (so you have to download part 1-6 then build the entire video yourself).
2). Cameraman talking during film. There is nothing remotely interesting to be discussed during the filming of a porn and if someone is behind a camera they should keep their mouth shut.
3). Useless camera work combined with bad video compression makes for useless porn.
4). Girls with assholes made by a shotgun blast. I can understand occupational hazards but porn is meant promote masturbation not start debates on forensic science. See ladyboycock.com for details.
5). The bald guy with the blonde goatie. It's fashionable to hate him.
6). Girls with silcone in their dicks. I love a big dick just like the next girl, but this cruelty to genetalia.
7). Execessively hair men. Do girls really like this?
