The lack of movement and expression by the female performers
You would think that if a girl is going to call herself an "Actress" then maybe she should try doing a little acting at least. Most of the porn today does feature decent looking actresses but if they could just act a little more like they enjoyed getting paid for what most of us would do for free them come on..... Shake that ass a little!!!!
I think that is why the MILF niche is so popular because most of those ladies are enjoying themselves and it comes across in their performances.
