Perve, you have every right to your opinion as do we. I think you would be surprised at the number of porn fans that don't really care for the gonzo stuff that is out there. Just because a performer doesn't do the gonzo stuuf doesn't mean that they suck as a porn performer. I am a long time fan of Jenna and I have NEVER found her films to be boring and get the impression that she is only doing the movies just for the money.
You say that you review porn for 3 sites and have been watching porn for 10-12 years as if that makes you some kind of expert. While I don't review porn for any sites my porn watching days go back to the days of Seka, that goes back about 20 years or so. In my opinion Jenna has been the biggest and best porn star of all time and I have seen plenty of them.
Also, sorry to tell you but if the porn industry relied mostly on the gonzo biz then the industry would be no where near what it is today. It would still be in a very small, dim lit, smelly store front in a run down part of town. Stars like Jenna have made the industry into what it is today.
