I see what you mean, and I completely understand your preference, but at the same time, I think the non-staff reviews are perfectly fine. We're a diverse forum with people form all over the world, of different backgrounds and different music tastes - so if it's "all over the place", then I would say good to that! Personally, I appreciate anyone who's willing to come and share their musical perspectives on here. It's great to see so many different outlooks, writing styles, and personalities in the reviews.
We're open to taking suggestions for reviews, but we try to stick to reviewing music that we personally feel strongly about, whether positive, negative, or what have you. Otherwise, writing reviews could become a soulless chore.
Personally, I'd rather read reviews by someone who has a genuine interest in the music and is invested in it to some degree. For instance, I am not too big on visual kei, so while I'm sure some people might still be interested in my thoughts on certain VK releases, I don't feel my perspective on the matter would be as relevant as some others here. I think most of my fellow ORZ members also feel the same.
